7 inch LED Headlights - Buyers Guide 2021

March 06, 2021 11 min read

LED headlights are very easy to install and upgrade to. Since most cars have halogen headlights, it's easy to be confused about the differences between LED headlights and other types of lights.

When you upgrade to new headlights, you'll want to make sure they are DOT approved. Whether you're taking a Jeep Wrangler off road, or you are just interested in daytime running lights, DOT does all of the approval for legal running lights.

Benefits of LED Headlights

  • 80 percent more efficient. The best LED headlights for trucks and cars will protect and preserve your vehicle's battery, which will make it last longer.
  • Last five times longer than halogens. The best LED replacement headlight bulbs last 30,000 hours or more. In comparison, you would need to change five or more halogen bulbs for a single LED bulb.
  • Cheaper over time. While the best LED headlights may cost more straight out of the box, you will save money in the long run because you won’t need to change the LEDs as often.
  • Brighter than halogens. The best LED headlight conversion kit offers superior performance compared to halogen lights, which may have light beams that look foggy or contain dark spots.
  • Illuminate the road better. When you drive at night, LED headlights enable you to see the road over greater distances than halogen bulbs. They also have anti-glare features.
  • Easy to install. In general, it takes 20 minutes or less to install LED headlights on most cars, SUVs and trucks. (This excludes older models, which may take more time.)

Types of LED Headlights

Dual Beam

All trucks, cars, and SUV headlights have high and low beams. A dual-beam bulb is a single bulb that performs both functions. With dual-beam headlights, there is only one bulb per headlight housing. For example, the best h13 LED headlight bulbs can be used on vehicles with dual beams.

Single Beam

A single-beam headlight bulb has one single function. One bulb creates one beam, either the high or low beam. If you want to replace both the high beam and low beam with LED bulbs, you will need two bulbs for single-beam headlights. The best h11 LED headlight bulbs are commonly used for the low beams. Due to wiring differences, single-beam and dual-beam headlights can’t be interchanged. 

LED Headlight Pricing

  • Under $50: LED lights in this price range may be bright or super bright but may have lower lumens and shorter lifespans than pricier brands. Still, there are many good-quality LED headlights available for under $50.
  • $50-$100: These LED headlights typically have higher lumens and are capable of lighting up the road far and wide, but they will cost a little more.
  • Over $100: These LED headlights are generally better in quality than less-expensive versions and can have up to 10,000 lumens and really long lifespans, but you will pay the most for these features.

LED headlights last longer and are more energy efficient than standard halogen headlights.

Key Features

Lumens

A light's intensity and strength is measured in lumens. Lights with 6,000-6,400 lumens (small intensity) illuminate the road over 500 meters in a straight line and are adequate for most drivers. Lights with 8,000 lumens (medium intensity) illuminate the road 600-700 meters in a straight line. If used with bright and super bright colors, they create an intense light beam. Lights with 10,000 lumens (high intensity) brighten the road almost as much as daylight.

Lifespan

Most LED headlights last between 30,000 and 50,000 hours compared to halogen lights, which typically last 6,000 hours. Top-rated LED headlights that last 30,000 hours work for about three years, due to a cooling fan or chip in the assembly. Lights that promise 50,000 working hours typically last at least six years, but they may be harder to find.

Other Considerations

  • Compatibility: It's crucial that you check your owner's manual to determine which LED bulb plug types and models will fit correctly in your vehicle. You may need to replace the entire headlight or use a conversion kit to make the change. Don't purchase a product until you are certain it will be compatible with your car or truck.
  • Colors: LED colors are measured in nanometers (nM), while white LEDs are measured in Kelvin. The higher the number, the cooler the color. Most headlights are bright colors and between 3,500 and 5,000 Kelvin. They let you see a good distance down the road and nicely illuminate the surrounding area. Super bright colors (above 5,000 Kelvin) are also known as Cool or Daylight White. They provide the widest and furthest views but may strain the eyes.
  • Warranty: Most LED headlight brands have two-year warranties for their customers. This is reasonable considering that the best LED headlight bulbs last at least three years. Some manufacturers will even offer three-year warranties, demonstrating that they stand behind their products. Also, check to see if the company offers technical support.

Other Benefits To LED Headlights

LEDs appeal to automakers and consumers for several reasons: They’re brighter than halogen headlights and often cast a wider pattern, plus they use less energy, last longer and have a much whiter color than halogens, which typically are yellowish. What’s more, a lot of people think they look cool.

Halogen headlights were the standard for the auto industry for years because they were cheap to manufacture and simple to replace, but now LEDs are outshining them.

Here’s how they’re different: Halogens are incandescent lights that have a tungsten filament inside a bulb. When electric current passes through the filament, it heats up and generates light. They differ from regular incandescent bulbs in that they have a dose of halogen gas instead of argon gas. Halogen bulbs are brighter than regular incandescent bulbs and tend to last longer.

With LEDs, an electric current passes through a semiconductor (or diode) to produce light that is brighter and generates less heat. LEDs operate about 90% more efficiently than incandescent bulbs, and because they generate less heat, that helps them last much longer than other types of lights. LEDs also typically don’t burn out like incandescent bulbs, though they do dim over time.

Because LEDs are smaller than bulb-type lights, they allow more design freedom with headlights and other vehicle lights. The downside is that they are more expensive than halogens or high-intensity-discharge headlights, which typically use xenon gas.

Are LED headlights worth it?

LED headlights offer an improvement over their halogen counterparts. The most important of these is greater visibility. LED headlights are much brighter, revealing more of the road and your surroundings. This benefit also goes two ways, as oncoming traffic will have an easier time seeing your vehicle.

You may also be wondering about the cost. It’s true that LED headlights tend to cost more than standard replacements. However, you should come out ahead in the long term as LEDs are more energy efficient and may last longer than halogens. That means less strain on your vehicle’s battery and less money spent on replacement bulbs.

Looks are subjective, but LED headlights can also help freshen up an older vehicle. LEDs replace the warm, yellow glow of halogens with brighter, cooler light found in modern cars. For maximum effect, be sure to clean and polish your headlights. All you need is toothpaste and a soft cloth for a quick DIY.

How do I install LED headlights?

If you can change a lightbulb at home, you shouldn’t have much trouble changing the headlights in your car. There are a few extra steps and it may take a few minutes, but the process is simple as LED bulbs can be directly swapped. You’ll need your new bulbs and a soft cloth or glove.

The bulbs are accessible from your vehicle’s engine bay, so start by popping open your hood. Remove the cover protecting the headlight assembly. Then, undo the clip holding the bulb. Carefully remove the old halogen bulb using a soft cloth or glove. Follow the steps in reverse, then repeat for the other headlight.

After installing both headlights, test them before going for a drive. If your turn signals blink too quickly after installation, your car may not properly detect the bulb, since LEDs draw very little power. You may need to install an LED bulb resistor, which requires a little wiring know-how. Don’t be afraid to call a professional.

Before You Buy

Cars come in all shapes and sizes, and so do headlights. That means you’ll need to make sure that the LED headlights you want are available and compatible with your vehicle application.

If your vehicle is equipped with high-intensity discharge (HID) headlights from the factory, changing to LED is more complicated. HID systems have some proprietary parts, so you’ll need to convert your lighting system to be LED compatible before swapping in LED bulbs. For this reason, we don’t recommend upgrading HID headlights to LEDs.

Breaking down LED colors and light purposes

White

  • White is the natural light color emitted from LEDs and closely resemble natural sunlight. White LEDs are the brightest and are an excellent way to significantly improve visibility on the road at night. The light output and color will be identical to that of luxury vehicles equipped with LEDs such as BMWs and Audis.

Yellow

  • LEDs with a yellow lens will produce a color similar to halogen bulbs and fog lights but with significantly more light output. This color is recommended for those looking to to increase the light emission from their headlamps/fog lights while maintaining the same color as their stock halogen bulbs. We recommend yellow LEDs for fog lights.

Blue

  • Blue LEDs produce an ocean blue color that can be suitable for both a stylish look and improved nighttime driving. This color is ideal for those looking for a perfect balance between improved brightness and a stylish look.

Purple

  • Being a dark color, purple LEDs are unquestionably the least bright and are to be used solely for a stylish, street racer look.

What is the brightest LED headlight color?

The brightest LED color for your car's headlights and fog lights is white, approximately equivalent to a 5500K bulb color temperature in HIDs. Although the light output is the same for each color, the human eye responds better to a white light similar to natural sunlight.

As mentioned above, LEDs generate light through a material that emits photons of light when charged. The light output (brightness) of LEDs is proportional to the amount of charge that's applied, therefore, the higher the charge the brighter the light emitted from the bulbs.

The charge, measured in watts (W), is provided by the LED drivers also known as the LED electrical circuits, which is the power supply. Our LED headlight and fog light conversion kits come with three LED wattage options 25W, 35W, and 45W.

For maximum brightness and the ultimate nighttime driving experience, we recommend going with our 45W LED kit in white, which produces an exceptionally powerful, dense and wide bright white light.

What is the best LED color for automotive headlamps?

The majority of people looking to upgrade and convert their headlights from halogens to LEDs are looking to improve nighttime visibility on the road, in which case, the best LED color is white. However, the 'best' color is subjective and entirely depends on your needs and ultimate outcome from upgrading your lights. The following summarizes the best LED color for different purposes:

  • Maximum brightness: White
  • Nicest style: Blue and purple
  • Imitating stock lighting: Yellow

Blue & Purple LED Headlights

Blue and purple LED headlights are becoming increasingly popular despite being the least bright. Below, we take a closer look at the main advantages and disadvantages of blue and purple LED headlights and fog lights. 

Pros of blue and purple LED headlights

  • Stylish and expensive look
  • Unique headlamp colors

Cons of blue and purple LED headlights

  • Least bright LED colors
  • Not recommended for fog lamps
  • May be illegal in certain jurisdictions
  • Ineffective during fog, snow and rain

Best LED color for fog lights

If you are looking to upgrade your fog lights to LEDs we recommend going with white or yellow. We strongly recommend against using blue or purple bulbs for your fog lamps for your personal safety in times of poor visibility (fog, haze, rain, snow, etc.).

Glossary of important lighting terms

  • Lumens (lm): measure of light output and brightness
  • Watts (W): measure of electrical power output
  • LED: light emitting diodes
  • HID: high-intensity discharge

What are the Differences Between Halogen and LED Headlight Bulbs?

The vast majority of vehicles leave dealership lots these days with one of three headlight bulbs: halogen, HID, or LED. Halogen bulbs are the oldest of the three and are still very common. They’re extremely affordable and typically have a life of around 800 hours on average. When compared to HID or LED bulbs however, halogen bulbs are the worst performing of the three. They also require more energy than LED bulbs and are more prone to heat. At the end of the day however, halogen bulbs offer enough lighting for safe driving, but upgrading to LEDs will make a noticeable difference to your driving experience.

LED headlight bulbs are becoming more commonly used by luxury automakers such as Audi, BMW, and Mercedes-Benz. You’ve also likely heard of LED bulbs for home use, which deliver equal or better lighting with lower power consumption and longer life. LED headlight bulbs are similar, offering better performance and longevity at a greater cost. Fortunately they’ve become so popular and common these days that they don’t cost significantly more than halogen bulbs.

Some will argue that LED headlight bulbs aren’t as bright as HIDs, but they are definitely brighter than halogen bulbs. They also don’t produce as much glare as HID headlights, and they don’t need a small period of time to charge up. Just as important, LED bulbs don’t use a filament that burns out or breaks, which allows them to last much longer than halogen bulbs.

Can I Upgrade to LED Headlights from Halogen Headlights?

The short answer to this question is yes. The aftermarket and the products in this list are designed to be retrofit kits for vehicles with halogen headlights. What’s important to know however is that some LED headlight kits may not be legal in your state. So make sure to check local state laws before upgrading to LED headlights.

Do I Need to Replace Both Headlight Bulbs at the Same Time?

There is actually no definitive answer to this question, but we recommend replacing both your headlight bulbs at the same time, even if only one goes out. That’s because swapping out just one headlight bulb could result in a difference in brightness between the two. Also, depending on your vehicle, changing out your headlight bulbs could be a cumbersome task—you’re better off doing it once and saving yourself time down the road.

If you’re trying to be frugal or more practical—if it’s not broken, why fix it—then make sure you keep a spare bulb handy for when the other one does eventually burn out.

Other Factors To Consider

Sealed beam headlights are different than LED headlights, and there are adapters, halo rings, and many other types of lights to also consider. 7 inch round LED headlights will provide different light than other types and sizes.

For your particular vehicle, it may be better to get a lo beam headlight, or even choose custom tail lights. You may need a reflector, or even something chrome, and you should also consider the beam pattern of the headlights you are buying.

If you're driving a classic car, you may need 2pcs for lighting, or LED headlights may not work at all for you. Sometimes an H13 adapter can be helpful, and brands like Cree also make Halo headlights.

There will also be different headlights unique to each vehicle. For example, if you're driving a Harley Davidson, the lights will be different than the lights on a Jeep Wrangler JK. A Hummer will have different lights, and an LED headlamp for a motorcycle headlight will look different than one on a car.

It's also important to note the differences between headlights. For example, a projector headlight will be different than a high low beam. A round sealed beam will be different than that, and some headlight kits will even be plug and play.

If you have a Rubicon, you'll also need different headlights, compared to the lights needed for a Sahara. You'll also want to look at different factors, like DRL, RGB, angel-eye, and other choices.
