What Are LED Headlights?

LED headlights use light-emitting diodes—small semiconductors that give off bright light instantly when electricity passes through them. These new lamps cast a white, sharp beam of light without the heat of traditional bulbs, which are much more energy-efficient. LEDs give off light very close to daylight, which improves night vision and color recognition. In newer vehicles, the diodes are typically part of the headlight assembly itself rather than replaceable bulbs. This fusion enables upscale features like adaptive beams that adjust based on driving conditions and create distinctive light patterns that characterize modern upscale vehicles.

What Are Halogen Headlights?

Halogen headlights are an older light technology found on the majority of cars for decades. Their functionality is actually quite simple: electricity is used to heat the filaments of tungsten within a compact bulb filled with halogen gas, which generates light. These bulbs have that classic warm-yellowish color that instantly characterizes a light source in a dark roadway. The filaments burn brighter and hotter than regular incandescent bulbs since the halogen gas prolongs its life. They're the traditional, easily replaced bulbs that screw into your vehicle's headlight assembly and have been standard equipment on most vehicles until recent years.

Halogen vs LED Headlights: Feature Comparison

Pros and Cons of LED Headlights

If you're wondering whether upgrading to LED headlights is worth the investment, here's what you need to know about their strengths and limitations before making your decision.

Pros:

  • Better Brightness: LEDs produce significantly more light (1,600+ lumens) than halogen bulbs, providing you with whiter, brighter light that's nearer to daylight.
  • Energy Efficiency: LEDs consume about 80% less power than halogen bulbs (15-20 watts vs. 55 watts), which reduces the electrical load on your car's system and can result in improved fuel efficiency.
  • Longer Lifespan: With an operational life of 20,000-50,000 hours compared to halogen's 500-1,000 hours, LEDs can potentially outlive your car's life.
  • Instant Lighting: As opposed to halogens, which gradually heat up to full brightness, LEDs hit full output the instant they are turned on.
  • Enhanced Safety: The broader, longer light throw (up to 300 meters, as opposed to 100 meters for halogens) provides more reaction time and better visibility under poor conditions.
  • Fresh Aesthetics: LEDs' distinctive, sharp light pattern gives vehicles a modern, high-end appearance.

Cons:

  • Higher Upfront Cost: Good quality LED headlights can range from $40-$120+ per pair, whereas halogens are available for $10-$50, making it a substantial initial investment.
  • Heat Management Needed: Though LEDs emit less heat in the front, they do emit heat at the base, which needs to be managed using good quality heat sinks or cooling systems to avoid damaging the internal components.
  • Complex Replacement: The majority of LED systems are integrated into the headlight assembly and hence are more complicated and expensive to replace compared to replacing a halogen bulb.
  • Performance in Fog: The intense brightness of LEDs sometimes produces more glare in foggy or snowy conditions due to light reflection off moisture particles.
  • Compatibility Issues: In certain vehicles, an upgrade from halogen to LED may need additional adapters or modifications, which may add complexity to the installation.

Pros and Cons of Halogen Headlights

Halogen headlights have been the industry standard for decades, and understanding their strengths and limitations can help you determine if they remain the right choice for your vehicle needs.

Pros:

  • Affordability: Halogen bulbs are far less expensive than modern alternatives, typically costing as little as $10-$50 a set, so they're affordable to replace.
  • Universal Availability: Halogen bulbs are widely available at almost all who retail auto accessories, from gas stations to auto parts stores to online retailers, so you'll never be more than a few miles away from a replacement.
  • Easy Installation: The majority of halogen bulbs feature a simple twist-lock mechanism that offers tool-free replacement within minutes, which is easy even for drivers with minimal mechanical skills.
  • Better Performance in Fog: The lower intensity and warmer color temperature of halogen light create less glare when reflected off water droplets, which provides better visibility in fog or mist.
  • Well-established Technology: Halogen technology is so familiar that almost every mechanic and even some car owners can diagnose and fix lighting issues without training.

Cons:

  • Limited Illumination: With only about 1,100 lumens and a yellowish color (about K color temperature), halogens are far less capable of lighting the road than more modern choices.
  • Frequent Replacement: With a typical lifespan of just 500-1,000 hours, halogen bulbs often require replacement every 1-2 years, depending on how much you drive at night.
  • Energy Inefficiency: Halogen bulbs consume approximately 55 watts of power while converting only 10% of that energy to light—the rest is wasted as heat, placing greater demand on your vehicle's electrical system.
  • Shorter Projection Distance: The light typically only travels about 100 meters (328 feet) ahead, providing less reaction time than with more modern lighting technology.
  • Old Appearance: The yellowish hue of halogen lights can make cars look old compared to the clean, white light of newer lighting technology.

Which Headlight Is Better for Different Driving Conditions?

Selecting the right headlight technology depends largely on where and how you drive. Different environments and driving scenarios create unique visibility challenges that certain headlight types address better than others.

1. City Driving

  • Best Choice: Premium halogen or mid-range LED headlights
  • Why: City environments have abundant ambient light and lower speed limits, reducing the need for maximum illumination. Here, you want balanced light that won't create excessive glare for other drivers.
  • What to Look For: Look for models with precise cutoff patterns that minimize upward light scatter. Note the fact that several municipalities have provisions for headlamp brightness and color temperature in towns, so your LEDs must be properly directed lest they blind oncoming traffic at an approaching stop sign and during crowded traffic conditions.

2. Highway Driving

  • Best Choice: High-quality LED headlights
  • Why: Highway driving demands longer visibility distances, making LEDs ideal with their ability to project light up to 300 meters ahead versus halogen's 100 meters.
  • Good to Know: Use LEDs with a minimum K-K color temperature and + lumens output for best highway performance. These systems' instant-on ability delivers full brightness immediately upon exiting tunnels or shadowed overpasses, while halogens take time to build to full output—a real safety benefit at highway speeds.

3. Off-Road Driving

  • Best Choice: High-output LED systems with supplemental lighting
  • Why: Off-road environments require both distance illumination and peripheral lighting to spot obstacles and terrain changes.
  • Worth Noting: For serious off-road use, installing LED light bars or supplementary spotlights at multiple heights to supplement your headlights is a good practice to gain better depth perception in challenging terrain—especially helpful for nighttime travel through obstacles.

4. Rural/Country Roads

  • Best Choice: LED headlights with adaptive features
  • Why: Dark country roads with potential wildlife hazards benefit from LEDs' longer throw distance and broader coverage area.
  • Pro Tip: Invest in systems with adaptive front lighting that can adjust beam patterns according to steering input, providing enhanced illumination around the rural road bends. Be aware that the brutal contrast between LED brightness and surrounding blackness can cause fatigue on long rural journeys; many high-end LED systems now incorporate anti-fatigue technology specifically designed to reduce this effect, so they're worth paying extra for regular rural users.

5. Poor Weather Conditions

  • Best Choice for Fog: Selective yellow halogen or yellow-tinted LED fog lights (K-K)
  • Best Choice for Rain/Snow: LEDs with precise beam cutoff
  • Why: Lower color temperatures produce less backscatter in moisture-laden air. In fog specifically, halogen's warmer output creates less reflective glare off water particles.
  • What to Look For: For dedicated fog lights, consider JDM Yellow bulbs or applying Lamin-X yellow film over LEDs to improve visibility in heavy mist conditions. Many modern vehicles allow selective activation of fog lights independent from headlights, letting you optimize visibility as conditions change—a feature worth considering if you frequently drive in areas prone to rapid weather shifts or morning fog.

6. Night Driving on Unlit Roads

  • Best Choice: High-performance LED headlights
  • Why: Maximum illumination distance and width becomes critical when ambient light is absent, making LED's superior output essential.
  • Good to Know: Select LED systems with high luminous intensity and color temperatures around K-K for optimal night visibility without causing eye fatigue. LEDs' color rendering index (CRI) better approximates daylight, improving contrast recognition of roadside hazards and reducing night driving fatigue over long periods—particularly valuable for rural commuters or those who frequently travel between cities after dark.

When making your final decision, consider the primary environments where you drive most frequently and choose a lighting solution optimized for those conditions. Many drivers with varied driving needs find that LED technology offers the best overall performance across different scenarios, despite the higher initial investment.

How Do LED and Halogen Headlights Compare in Environmental Impact?

Headlight technology affects more than just your visibility—it impacts your car's environmental footprint too. LED and halogen headlights differ significantly in their environmental effects throughout their lifecycle. Here's what eco-conscious drivers should know when choosing between these options.

Environmental Impact Comparison: LED vs. Halogen

Factor Halogen Headlights LED Headlights Energy Efficiency Converts only 10% of energy into light, wasting 90% as heat Converts up to 90% of energy into light with minimal heat waste Power Consumption Typically 55-65 watts per bulb Typically 15-25 watts per bulb Lifespan 500-1,000 hours (1-2 years) 15,000-50,000 hours (15+ years) Waste Generation Frequent replacement needed Rarely needs replacement Hazardous Materials No mercury, uses halogen gases No mercury or toxic gases Recyclability Limited recyclability Better recyclability, though circuit boards are challenging Manufacturing Impact Simpler production, lower initial resources More complex manufacturing, higher initial resources Vehicle Efficiency Increases fuel consumption by 0.1-0.2 mpg Improves fuel economy by up to 0.2 mpg Carbon Footprint Higher lifetime emissions Lower lifetime emissions overall

LEDs win the environmental contest despite their more resource-intensive manufacturing. Their dramatically better energy efficiency and much longer lifespan mean significantly lower environmental impact over time. One set of LED headlights can replace up to 30 halogen bulbs during your car's lifetime, reducing waste and saving fuel. For most drivers looking to make their vehicle greener without sacrificing safety, LED headlights are one of the simplest and most effective upgrades available.

What Should You Check Before Buying New Headlights?

Before rushing to upgrade your headlights, taking time to consider several key factors can save you money, frustration, and potentially legal issues down the road. The right headlight for your vehicle depends on more than just brightness—compatibility, light characteristics, longevity, and regulations all play important roles in making a smart choice.

1. Will These Headlights Fit My Car?

  • What to Check: Ensure the headlights physically fit your exact car model, make, and year. Check the bulb type code on your current headlight (such as H11, , or H7) or refer to your owner's manual.
  • Why It Matters: The greatest headlights will be useless if they don't fit into your housing. Most online retailers offer vehicle-specific lookup functions that can double-check compatibility before buying.

2. How Bright Are These Headlights?

  • Good to Know: Brightness is measured in terms of lumens—larger numbers equal brighter light. Most halogen bulbs produce 700-1,500 lumens, while LEDs produce 2,000-10,000 lumens.
  • Quick Tip: Not everything that shines brightly is best. Extremely bright headlights can blind oncoming traffic and can even be banned. For everyday driving, 2,000-4,000 lumens provide great visibility without excessive glare.

3. What Color Will My Headlights Be?

  • What Works Best: Color temperature (in Kelvin) determines whether light is yellowish (K), neutral white (K-K), or bluish (K+).
  • Practical Choice: Most drivers like K-K as the best compromise between visibility, low eye strain, and natural color rendering—such as natural daylight.

4. How Long Will These Headlights Last?

  • Worth Noting: Halogen bulbs have a lifespan of 500-1,000 hours of use (about 1-2 years of normal driving). LEDs have a lifespan of 15,000-50,000 hours—sometimes longer than the vehicle itself.
  • Cost Consideration: While LEDs are more costly upfront ($40-150 for a pair vs. $10-30 for halogens), their extended lifespan means fewer replacements and perhaps less long-term cost.

5. Are These Headlights Legal to Use?

  • Important Warning: Headlight modifications must comply with Department of Transportation (DOT) regulations. Look for "DOT approved" markings on the packaging.
  • Buyer's Tip: Some LED "upgrades" designed for halogen housings create improper beam patterns that can blind other drivers and fail safety inspections. Choose bulbs specifically designed to work with your existing housing type without causing excessive glare.

6. How Hard Are These Headlights to Install?

  • Shop Smart: Halogen replacements are typically simple DIY jobs. LED upgrades might require additional wiring, heat sinks, or voltage regulators depending on your vehicle.
  • Before You Buy: Check if installation requires special tools or professional help, which adds to the total upgrade cost. Many modern LED options offer plug-and-play installation with no modification needed.

When making your final decision, balance these factors based on your specific needs and budget. Remember that the best headlight is one that offers improved visibility while respecting other drivers on the road. If you are uncertain about installation or legal compliance, consulting with an automotive lighting specialist can help ensure you make the right choice for both safety and satisfaction.

LED vs. Halogen Headlights: Your Most Common Questions Answered

Q1: How bright is a 20W halogen?

A 20W halogen bulb will typically produce about 300-400 lumens. That's very dim for headlights, as standard automotive halogen headlight bulbs are closer to 55-65W and produce 700-1,500 lumens.

Q2: Are halogen or LED headlights better?

LED headlights outperform halogens in all respects. They're 4-5 times more efficient, last 15-30 times longer (often longer than your vehicle), are more visible, and operate cooler. Halogens only win on initial cost—they're typically $10-30 per pair versus $40-150 for LEDs.

Q3: Is it illegal to replace halogen headlight bulbs with LEDs?

In most places, yes—except if you are installing LED bulbs that have specifically been certified for your halogen housings. Standard LED retrofits will create inappropriate beam patterns that blind other drivers. Look for bulbs that are DOT/SAE certified for legal use in halogen housings, and always check your local laws prior to upgrading.

Q4: What is the LED equivalent of a 20-watt halogen bulb?

A 4-5W LED is as bright as a 20W halogen. LEDs convert electricity to light about 4-6 times more efficiently, so you need so much less power to get the same brightness.

Q5: A 50-watt equivalent for halogen LED is what?

A 50W LED would have the same illuminating power as a 250-300W halogen headlight—hugely, hugely bright to use in your car. Almost all LED headlights actually only need 15-25W of power and create more brightness than 55W halogens.

Q6: What is the equivalent of 25W halogen in LED?

A 25W halogen bulb (around 400-500 lumens) equates to roughly a 5-7W LED bulb when it comes to light.

Q7: Are there halogen headlights as bright as LED?

No, even performance halogens can't keep up with mid-range LEDs because of the technological physical limitations. The most powerful halogens reach only around 1,700 lumens, whereas standard LED headlights emit 2,000-4,000 lumens. Halogens would need unreasonable amounts of power to achieve LED-level intensity and would generate deadly levels of heat.

10 Proven Tips to Choose LED Headlight Bulbs for Your Vehicle

Installing LED headlights has many advantages over HID and halogen, such as brighter light, longer lifespan, and lower energy consumption. There are various LED car bulbs on the market. They are either high power or low power, expensive or low price. What factors should be considered when finding so many brands and types of LED headlight bulbs for the cars. What specs to look for when selecting LED headlight bulbs for car? What are the most important specs for LED headlight bulbs?

These are the most frequently asked questions by customers looking for LED headlight bulbs are also the most strategic questions for auto manufacturers to keep in mind while designing, manufacturing, testing, and improving LED bulbs.

It is said that choosing the best might not be the best choice. Here in this blog, we’ve come up with seven tips to be considered before choosing the most appropriate LED headlight bulb for your car.

1. Brightness

The first thing to consider is the brightness and light distribution produced by the bulbs. To have brighter bulbs means better visibility for night-time driving. It could be helpful for those who have problems seeing clearly at night.

“Lumen” is a standard unit of measurement for brightness. The brightness of LED headlights will also depend on the wattage of the bulbs. One wattage diode is capable of emitting around 130 lumens. Generally, the higher the lumen rating, the brighter the bulbs. The brighter the headlight bulb, the higher the price.

Most LEDs are designed to reach between 8,000 and 13,000 lumens range whereas 2,000-4,000 lumens are the most common range for typical manufacturer headlights. It would be wise to note that headlight bulb manufacturers advertise a lumen rating such as 12,000; Actually, they are the combined rating for both bulbs - meaning each bulb is 6,000 lumens.

Manufacturers widely use total lumens during the LED bulb design and is often measured by an integrating sphere after the bulb has been made.

2. What are the best light beam patterns?

(NAOEVO ND LED headlight bulb standard high beam and low beam)

Light beam pattern refers to the light angle and shape emitting through the headlight housing. Light beam patterns are as important as brightness and directly related to driving safety. Quality LED headlight bulbs to emit a distinct 45 degrees cut-off line on low beams and focus on high beams.

Low beams without any dark areas have two main benefits. On the one hand, they are helpful to see the oncoming traffic clearly without shining the eyes of other drivers.

On the other hand, perfect light beam patterns are contributed to a broader vision for drivers at night driving. They can see clearly on both sides of the road and react sooner to the accident.

In some right-hand driving countries, the light beam pattern should be lower on the left and higher on the right, and vice versa.

3. LED Radiation Characteristics

There are different LED light chips with different shapes and positions of LED beads. They will all affect the light beam pattern. Quality LED light chips are supposed to mimic the original filament, and the spacing between both sides of beads should be as close to the width of the original filament as possible.

Looking at the above two pictures of the LED headlight, the footprint of the LEDs is too broad, and the space between the two sides of the LED is also too wide. Having spaced out too far and your beam pattern will be out of focus with no hot spot and cause glare to others on the road.

Are you looking for LED headlight bulbs that have a narrow LEDs array? One great example is the NAOEVO S3 LED headlight conversion kit. The metal between LED is extremely thin, allowing the LED position to be as close to the original halogen position as possible.

4. What color temperature is better for driving?

Every light has a color temperature. Color temperature is conveyed in units called “Kelvin.” It can conclude that a Lower Kelvin rating means you have a yellow or orange light, which is called warmer color temperature. A Higher Kelvin rating means you have a whiter and more blue light. It is a cooler temperature.

Everyone perceives color differently, and different color temperatures change your perception of the object you are looking at. The natural light source during daytime belongs to a high color temperature. Our brain will be more energetic and ease eye strain under such a high color temperature illumination.

Usually, the sunlight is measured as a K color temperature. While this K is closed to daylight, providing a noticeable difference in brightness that shows a fantastic driving performance. Therefore, LED headlight bulbs on the market illuminate -K color temperatures are better for night-time driving.

However, in some countries, rainy and foggy days are frequent. In this case, having LED car light bulbs perform well in all bad weather conditions is crucial for road safety. Check out the latest S4 LED headlight bulbs from NAOEVO. These bulbs integrated three colors and a flashing model. They are built to satisfy all your driving demands.

5. LED headlight bulb lifespan

People long ago thought that LED light bulbs didn’t cause much heat as long as they were just a little blinking light on your dashboard. But now, they are trying to create brighter light by consuming much energy. They do create heat!

For more information, please visit halogen vs led headlights.

The lifespan of LED headlight bulbs is highly relevant to the methods of heat dissipation. If the heat dissipation is poor, everything else is empty talk, such as the brightness. When LED headlights are working, most of the heat is generated by the complex circuit board at the base of the diodes.

There are three types of heat dissipation methods for LED headlights: 1. Pure aluminum heat sinks 2. Fan cooling 3. Copper tape cooling.

There are three basic theoretical methods of heat dissipation: 1. Conduction 2. Convection 3. Radiation

LED headlight bulb with pure aluminum heat sink is made from alloy aluminum. It helps to cool down the bulbs by thermal radiation of itself. More significant heat sink, then better heat radiation.

This fanless LED headlight bulb with a pure aluminum heat sink maintains a stable cooling capacity, but the power of the bulbs should be designed as low as possible, and the brightness will also decrease.

LED headlight bulbs with copper-strip heat sinks are made from copper wire with tin coating on the surface. Copper tape fins and wings are adjustable to maximize the area for heat dissipation.

However, all the wings can not be squeezed together, or the cooling performance will decrease. Besides, they are not 100% attached to the bulb body and are hard to install in the headlight housing.

LED headlight bulbs with high-speed fans are the most common cooling methods for headlight bulb makers. They take the initiative to dissipate the heat, which can ensure the regular operation of high-power bulbs.


The fan quality is vital for the lifespan of LED bulbs. Otherwise, the bulbs also cannot keep being used when the fan is broken.

(Max3 LED with heat pipe cooling solution providing three times higher thermal capability)

Quality LED headlight bulbs are capable of lasting over 50,000 hours. The premise is that they have reliable heat conduction. Thus, NAOEVO Max3 LED headlight bulbs have made a remarkably succeeded in this aspect. Max3 LED bulbs achieve efficient heat dissipation by being equipped with dual copper heat pipes technology, making an excellent balance of high brightness and cooling.

6. LED Headlight Bulb Brand

There are many poor-quality LED headlight brands on the market. Some of the cheap LED kits feature overclocked chip sets that allow them to produce a high lumen and create a large amount of heat for a very short time. It doesn’t take long for the whole headlight system to overheat and fail. In the description, they may claim the bulbs have 50,000 hours lifespan, but in fact, they can only last for 1,000 hours or less.

Buying LED headlights from a reliable brand is also a guarantee of product quality. Such as Osram and Philips are all well-known lighting companies with a centenary year of brand foundation. They offer five years quality warranty for some LED car light bulbs, but they will cost you an arm and a leg.

If you are looking for high-quality LED headlight bulbs at a reasonable price. NAOEVO is the best choice for you! They are one of the largest LED car light bulb manufacturers & suppliers in China. By introducing lots of high-tech machines for manufacturing first-class LED light bulbs in various styles, their products are widely exported to the USA, Europe, Southeast Asia, and South America and have obtained many customers’ high praises.

7. LED Headlight Bulb Chip

Another essential factor to take note of when purchasing LED headlights is the type of chip that is utilized. The LED chip is a core component of the entire LED headlight bulb, with the development of LED lighting and the high demands from customers. Many manufacturers strive to improve and innovate LED chips. Picking the correct type of LED chips allows the bulb to maximize brightness with the least amount of energy. Cree, COB, CSP, ZES, and ETI FC (flip-chip) are the most common available chips for LED headlight bulbs.

Cree

As a company since , Cree has been producing some of the best LED lightings on the market. While the original Cree no longer exists, its top-quality LED chips remain to exist on the market. These chips are designed with a small bubble for concentrating light.

Pros: Light efficiency, lower temperature
Cons: Cause scattered light beam

COB (Chip on board)

COB refers to the mounting of a bare LED chip in direct contact with a substrate to produce LED arrays. COB LED technology can significantly reduce the energy consumption of LED arrays while keeping light output constant. Another considerable merit of the COB chip is that its devices have only one circuit and two contacts for the entire chip, regardless of the number of diodes.

Pros: High illuminating power, homogeneous lighting
Cons: Poor thermal resistance, high price

CSP (Chip Scale Package)

CSP is defined as a LED package with a size equivalent to a LED chip. Despite its small size, it can produce high-performance light. Its superior quality without soldered wire connections or need for space makes it excellent in reducing thermal resistance and reducing possible failure points.

Pros: Micro-sized, medium power
Cons: Difficult in processing, not suitable for high-power products, high price

ZES

Lumileds Luxeon ZES once belonged to Philips. Designed with a simple inner structure, ZES has outstanding color consistency, luminance, flux density, and design flexibility for lighting solutions. ZES chip has a lower defective rate than other types of chips.

Pros: small size but high luminance, good to mimic the filament in halogen bulbs, good heat dissipation
Cons: Very expensive

ETI FC (Flip-chip)

Flip-chip is a newly patented technology. This type of chip mounts the LED diode upside down, which both shortens the production process and results in a higher heat dissipation rate. Flip-chip has become an increasingly popular choice of LED headlight bulbs.

Pros: High quality; better heat transmission; perfect light beam pattern; affordable price.
Cons: Higher requirement for the manufacturing process, difficult to maintain.

Other Factors

Bulb Size

Besides the above-mentioned tips, there’s one of the essential factors to think over when buying car headlights - whether the model fits the vehicle or not. In most cases, headlight bulbs are compatible with a wide range of models. The bulb models’ numbers are mainly divided into a single beam and dual beam functions. Still, confused about this section? Look for our previous blog, High Beams vs. Low Beams: Any Difference? to get more answers.

You can check out your car bulb size by looking at the user manual or searching the Car Bulb Finder tool for help.

The Legality of LED Bulbs

Every country has different laws that determine what makes the car bulb road legal. Consumers need to ensure that the headlights are permitted by law, road safety, and appropriate for traveling. There are also laws regarding the color of your headlights. Regardless of the region you live in, the law requires your headlight to be yellow or white. Some drivers may find that certain bulbs produce blue lights, which makes them non-road legal.

Upgrading with LED car light bulbs should also ensure that it carries RoHs, CE, and E-mark certifications, which comply with European standards. Or in the United States, it needs to be DOT-Compliant to follow US regulations.

IP Rating

The IP rating of a bulb determines the level of protection it has against dirt or water. The higher the IP rating level, the better the water resistance. The ratings most widely accepted as “waterproof” are IP65, IP67, and IP68. The difference between them is the degree of liquid ingress protection they offer.

IP65 Rating: Gives protection against low pressure as well as c

ondensation.
IP67 Rating: Offer more substantial protection against liquid ingress, and protect against temporary submersion.
IP68 Rating: capable of continuous immersion in water.

Conclusion

We hope that the above factors can this article can help you to find the best and the most appropriate auto LED light bulb for your car.
