11 Step-by-step Guidelines on How to Make Projector Headlights Brighter

Step 1: Clean the Headlights

The first step is to make sure your projector headlights are clean and free from dirt, dust, debris, and bug splatter. Use a soft cloth with an automotive cleaner and wipe down the surfaces of the projector headlights to remove any surface contaminants.

If you find any difficult-to-remove spots, use a plastic scrubbing pad to gently remove them. But make sure you don’t scratch the surface! Remember to clean both the inside and outside of the headlights.

Step 2: Check for Alignment Issues

The next step is to check if your projector headlights are properly aligned. If they are not correctly adjusted, this can drastically reduce visibility at night. To check alignment, park your car 25 feet away from a wall and make sure that the low-beam lights are aimed at the center of the wall.

It’s important to note that all four headlight lenses should be pointing in the same direction for optimal performance. This simple step will ensure that your beam pattern is evenly spread, resulting in a brighter and more effective lighting system.

Step 3: Upgrade Your Bulbs

If you find that cleaning and aligning don’t improve brightness significantly, then it may be time to upgrade your headlight bulbs. Upgrading from stock halogen bulbs to HID or LED bulbs can provide an increase in light output and make your headlights brighter.

Moreover, HID and LED bulbs are much more energy-efficient than halogen bulbs, so they’ll last longer as well. It’s important to note that you should always use bulbs that are compatible with your vehicle.

Use Bulbs That Are Compatible

Step 4: Install a Headlight Relay Harness

If you’ve upgraded to brighter bulbs but still want more brightness, then it may be time to install a headlight relay harness. This device is installed between the car’s electrical system and the projector headlights, allowing for more power to be delivered directly to the lights.

This increased voltage will result in brighter headlights that will last longer than those without the harness. But be sure to get one that is compatible with your car for optimal performance.

Step 5: Upgrade Your Reflectors

Another option is to replace the factory reflectors with aftermarket ones designed specifically for projector headlights. These reflectors will help to redirect light in the direction you need it and provide a brighter, more focused beam pattern. It’s important to note that installation of aftermarket reflectors requires some mechanical experience, so it’s best to leave this job to a professional.

Step 6: Install an Aftermarket Headlight Bezel

An aftermarket headlight bezel can also help your headlights shine brighter. This accessory adds style to your ride while also reflecting light back into the projector lens for increased brightness. This upgrade is relatively easy to install and requires no mechanical experience.

It’s important to make sure you get one that fits your vehicle and headlight type for optimal performance. It’s also a good idea to use professional-grade protective coating on the bezel to ensure that it lasts.

Step 7: Upgrade Your High Beam Bulbs

If you’re looking for even more visibility at night, consider upgrading your high beam bulbs as well. Lumens is a measure of how much visible light a bulb emits, so look for higher lumens ratings when selecting new high beam bulbs for maximum brightness.

This upgrade will give you more visibility on those dark roads, so be sure to get a bulb that is compatible with your vehicle. You may also want to consider adding a switchback LED bulb for added visibility.

Step 8: Install LED Halo Rings

LED halo rings are a great way to add extra illumination and make your projector headlights look modern and unique. These LED strips encircle each headlight and offer an additional level of light output that can significantly improve visibility at night.

It takes some technical know-how to properly install these, so it’s best to leave this job to a professional. Otherwise, you risk damaging the LED strips and reducing their lifespan.

Step 9: Install Aftermarket Shrouds

Installing aftermarket shrouds is another way to upgrade the appearance of your headlights while also increasing brightness. These plastic covers wrap around the projector lens and focuses light in the direction you want it to go for increased visibility. But it’s important to make sure the shrouds you select are compatible with your vehicle and headlight type for optimal performance.

Step 10: Add a Fog Light Kit

Adding a fog light kit is one of the most effective ways to increase the brightness of your projector headlights. This accessory adds two additional lights on either side of your vehicle that provides a wide spread of light for improved visibility.

It’s important to get a kit that is compatible with your car for optimal performance. Otherwise, you risk damaging the electrical system. But if the installation is done correctly, you’ll have a brighter and more effective lighting system than ever before.

Step 11: Check Your Wiring

Finally, always make sure to check your wiring before making any modifications to the headlight assembly. Loose wires or corrosion can reduce light output and should be addressed immediately. With proper maintenance and care, you can ensure that your headlights remain bright for many years to come. Always refer to your owner’s manual for specific instructions on how to properly check your wiring.

By following these steps on how to make projector headlights brighter, you can get those projector headlights shining brighter than ever before! Be sure to use caution when making modifications and always follow manufacturer instructions for best results. 

Now go out there and enjoy the night with bright, beautiful projector headlights!

Frequently Asked Questions

Q: How Do I Make My Projector Headlights Brighter?

A: There are several ways to make your projector headlights brighter. Cleaning, checking alignment, upgrading your bulbs, installing a headlight relay harness, upgrading your reflectors, installing an aftermarket headlight bezel, upgrading your high beam bulbs, installing LED halo rings, adding a fog light kit and checking wiring are all effective ways to make projector headlights brighter.

Q: Is It Worth Upgrading My Headlights?

A: Yes! Investing in better headlights can improve visibility and safety at night while also giving you the added bonus of improved styling. With the right upgrades and modifications, you can get those projector headlights shining brighter than ever before!

Q: What Is the Difference Between HID and LED Headlight Bulbs?

A: HID (high-intensity discharge) bulbs produce bright, white light that is similar to natural daylight. They are usually more expensive than traditional halogen bulbs but last longer and have higher luminous efficacy. LED (light-emitting diode) headlights are also energy efficient and provide a brighter, more focused beam pattern. However, they can be costly to replace due to their small size.

LED Headlights Are Also Energy Efficient

Both technologies offer great advantages when it comes to upgrading your projector headlights, so it’s important to consider both options before making a decision.


Projector headlights can make a big difference in the look and visibility of your vehicle. Not only that, but they can also give you better visibility in nighttime driving conditions. If you’re looking to upgrade to projector headlights, it’s important to note that these lights require a higher degree of brightness than stock bulbs do for optimal performance.

There are several ways to increase the brightness of your projector headlights, from adjusting the light level setting on your car’s control console, installing LED headlight bulbs or using high-wattage light bulbs, installing customized headlight halos and shrouds, as well as increasing reflectivity with retrofitted LED DRL bars.

With just a few simple steps on how to make projector headlights brighter, you’ll be able to enjoy improved lighting performance with your projector headlights! So don’t wait any longer – leave those common stock bulbs behind and start upgrading today!
