How To Make Your Headlights Brighter

Headlights are unquestionably one of the most important parts of any vehicle. In a sense, they act as your car’s eyes.

An IIHS study found that driving at night is 3 times more dangerous than during the day and that good headlights lead to nearly 20% less nighttime accidents compared to poor headlights.

In this guide, we'll show you how to brighten headlights using five easy methods for any car, truck, motorcycle, snowmobile, and ATV.

If your headlights are not bright enough, it's a major problem. Ironically, headlights have been one of the most neglected parts in vehicle manufacturing up until very recently.

The majority of cars, trucks, and motorcycles on the road simply have terrible headlight bulbs. They are dull, yellowish, and hardly illuminate the road.

Fortunately, there are brighter headlight bulbs that will completely transform your driving experience in low visibility environments.

Upgrade Your Headlight Bulbs

The best way to make your headlights brighter is by upgrading to brighter headlight bulbs.

There are 3 types of bulbs you can choose from to improve nighttime visibility while driving: LED, HID, and halogen.

Type Pros Cons

Very bright, long lifespan, long distance, wide range, easy to install

More expensive, vehicles w/ halogens only


Bright, good distance, wide range, color options

Fade over time, warm up period, more difficult to install, vehicles w/ halogens or HIDs only


Cheap, easy to install, direct replacement

Least bright, fade over time, short lifespan

Since the #1 reason for dull headlights is the bulbs it's only logical that upgrading the bulbs will help.

Let's take a closer look at each of the three types of bulbs you can choose from.

1. LED Headlight Bulbs

If your vehicle has factory halogen bulbs, you should seriously consider LED headlight bulbs.

LEDs are the brightest headlight bulbs. They are up to 700% brighter than halogen bulbs and last five to ten times longer.

Unlike halogens which emit a dim yellowish light, LED bulbs emit a pure white light, which dramatically improves nighttime visibility.

LED headlight bulbs fit right into your existing assemblies so the installation will be dead simple, even your grandma can do it.

For these reasons, upgrading to LED bulbs is the best way to get brighter headlights.

2. HID Headlights Bulbs

A second great option, if your vehicle has factory halogens, is to upgrade to HID (xenon) headlights.

HIDs are extremel`y bright, producing nearly 5 times more light than halogens and lasting up to 500% longer.

Although slightly more complicated to install, HID headlight bulbs fit right into your existing assemblies. They will unquestionably make your car lights brighter.

One thing drivers love about HIDs is that they come in a variety of color temperatures ranging from yellow (3000K - 4300K) to white (5000K - 6000K) to purple (8000K - 12000K).

If you have factory HIDs and you are wondering how to make your headlights brighter, there are a few considerations.

If your car is at least five years old, your bulbs may have started fading, and getting simple replacements should solve the issue.

Further, older cars may have dirty assemblies which impacts brightness as we cover in the next section.

3. Premium Halogen Bulbs

If you're on a tighter budget or not looking to change the type of bulb your vehicle uses, you can opt for premium-quality halogen bulbs.

Premium halogen bulbs will get you up to 25% more light and they even come in white or light blue, which will help you see better at night.

Although not nearly as bright as LEDs or HIDs, they are a viable and inexpensive option to consider.

If you have an older car with dirty assemblies, a bulb upgrade and a good scrub of your headlights can make a meaningful impact on your nighttime visibility.

4. Clean Your Headlights

If you're not happy with your headlights, it's typically because of your bulbs but it's not always the case.

As a car ages, so do its headlights. They get dirty, hazy, foggy, and scratched from moisture and dirt.

So even if you have the brightest bulbs in the world, it won't matter if the light can't get through.

Headlight Restoration Before & After

The good news is that it's usually quite easy and cheap to clean your headlight assemblies. It will not only improve your car’s light output but it will also make your car look much cleaner.

There are several ways of doing it with regular household ingredients (see the video below) or you can buy a headlight restoration kit for under $20.

It goes without saying that this method is only for older vehicles and that restoring your headlights can only restore the original brightness of your headlights.

Restoring your headlights and upgrading the bulbs will yield brighter headlights for older cars.

5. New Headlight Assemblies

Last but not least, putting in new headlamp assemblies!

Another great way to improve the brightness of your vehicle’s headlight is to completely replace your existing headlight assembly for either an LED or HID assemblies.

Headlight Retrofit Before & After

Although the most expensive option by far ($2,000+ when factoring in parts and labor), it is very effective. The process is known as retrofitting.

Nonetheless, a retrofit would upgrade your current lighting system to LED or HID and dramatically improve your lighting by up to 700% and give your vehicle a cool new look and feel.

Unlike LED or HID bulb upgrades, you'll need an expert to install these unless you're an expert yourself. There is quite a bit of wiring and electrical work to do.
