How To Restore Headlights

Dustin Hawley | Jul 06, 2023

Headlights are essential to your vehicle, providing illumination for safe driving. Over time, however, headlights can become discolored, clouded, and scratched, reducing their effectiveness and appearance. 

How To Restore Headlights

This article will explore why headlights become discolored, provide a step-by-step guide on restoring them, and discuss essential maintenance tips to keep your headlights looking new for years to come.

What Causes Headlights to Discolor?

There are several reasons why headlights may become discolored, including:

  • UV exposure. Headlights are exposed to the elements and UV radiation, which can cause the plastic lens to turn yellow, fade, and become cloudy over time.
  • Scratches and scuffs. Scratches and scuffs can occur on the surface of the lens, causing it to become cloudy, reducing visibility, and detracting from the appearance of your vehicle.
  • Dirt and grime. Dirt, grime, and other impurities can build up on the surface of the headlight lens, making it appear discolored and reducing visibility.

Step-by-Step Guide to Restoring Headlights

If your headlights have become discolored, cloudy, or scratched, there are several steps you can take to restore them, and they will be listed below.

Step 1: Clean the Headlights

The first step in restoring headlights is cleaning the lens's surface. Use a soft cloth and a mild soap solution, such as dish soap, to remove any dirt, grime, and other impurities. Be sure to dry the surface thoroughly to prevent water spots from forming.

Step 2: Sand the Headlights

If the surface of the headlight lens is discolored or cloudy, you'll need to sand it to remove the surface layer and restore the clarity. Use low-grit sandpaper, such as 1000-grit, and gently sand the surface of the lens. Be sure to sand in a circular motion and apply gentle pressure to avoid damage. Repeat the sanding process until the surface is clear and free of discoloration.

Step 3: Polish the Headlights

Once you've sanded the surface of the headlight lens, it's time to polish it to restore the shine. Use a polishing compound, such as toothpaste or baking soda, and a soft cloth to rub the lens's surface gently. As with the previous step, polish in a circular motion and apply gentle pressure to avoid damaging the lens. Repeat the polishing process until the surface is clear and shiny.

Step 4: Apply a Protective Coating

Finally, to prevent future discoloration and protect the surface of the lens, it's essential to apply a protective coating. You can use a clear coat, such as a UV-resistant sealant or car wax, to protect the surface of the lens from the elements and UV radiation. Apply the protective coating evenly and allow it to dry completely before using your vehicle.

Maintenance Tips for Headlights

To keep your headlights looking new, consider having a proper maintenance schedule, which includes taking care of the headlight in the following way:

  • Washing. Regularly wash the surface of the headlight lens to remove dirt, grime, and other impurities.
  • Protecting the headlights. Apply a protective coating to the surface of the headlight lens to prevent discoloration and protect against UV radiation and the elements.
  • Avoiding scratches and scuffs. Handle the headlight lens carefully to avoid scratches and scuffs. Store the headlight lens in a safe place when not in use to prevent damage.
  • Keeping the lens clean. Use a soft cloth and a mild soap solution, such as dish soap, to clean the lens regularly to prevent the build-up of dirt and grime.

Summary

Restoring headlights can improve the appearance and effectiveness of your vehicle. By following the step-by-step guide outlined in this article and practicing regular maintenance, you can keep your headlights looking new for years to come. 

If you're unsure about restoring your headlights or have any concerns, it's best to consult a professional to avoid damaging your vehicle. With the right tools, techniques, and knowledge, restoring headlights is a straightforward process that can be completed in just a few steps.
