Headlights are crucial for safe driving, especially at night or in poor weather conditions. However, over time, they can become scratched and foggy, reducing their effectiveness and your visibility on the road. Whether it’s from debris, road salt, or just wear and tear, scratched headlights can be a safety hazard. The good news is, you can restore them yourself with a bit of effort. In this guide, we’ll walk you through the process of fixing scratched headlights to keep them looking clear and working effectively.
Understanding Headlight Scratches
Not all headlight scratches are the same. Some are superficial and easy to fix, while others are deeper and require more effort.
Types of Headlight Scratches: Light vs. Deep
Light scratches are usually surface-level and can be polished out with minimal effort. These often come from dirt, dust, or small debris hitting the headlight. Deep scratches, on the other hand, penetrate the surface and may require more intensive sanding and polishing.
How Scratched Headlights Affect Visibility
Scratches scatter the light coming from your headlights, reducing the clarity of the beam and making it harder to see at night. This can also make your car less visible to other drivers, increasing the risk of accidents.

- UV sealant (if not included in the restoration kit)
Optional Tools for a Professional Finish
- Electric drill with polishing attachment (for faster and more consistent polishing)
- Headlight lens cleaner
- Protective gloves
Having these tools ready will help you achieve the best possible results with minimal frustration.
Preparing Your Headlights for Repair
Preparation is key to a successful headlight restoration.
Safety First: Ensuring the Vehicle is Off and Cool
Before you start, make sure your vehicle is turned off and that the headlights are cool to the touch. Working on a hot headlight can be uncomfortable and may cause the polishing compounds to dry too quickly.
Cleaning the Headlight Surface Thoroughly
Start by washing the headlights with soap and water to remove any dirt and grime. Dry them with a clean microfiber cloth. This step is crucial because any remaining dirt could cause more scratches during the repair process.
Step-by-Step Guide to Fixing Scratched Headlights
Now, let’s dive into the process of restoring your headlights.
Step 1: Assessing the Severity of the Scratches
Before you begin, take a close look at the scratches. If they’re light and mostly on the surface, you can proceed with polishing. For deeper scratches, you might need to use sandpaper.
Step 2: Using a Headlight Restoration Kit
A good headlight restoration kit typically includes everything you need: sandpaper in various grits, a polishing compound, and a UV sealant. Start by masking off the area around the headlight with tape to protect your car’s paint.
How to Apply the Kit for Best Results
- Sand the Headlight: If the kit includes sandpaper, start with the coarsest grit and work your way up to the finest. Keep the headlight wet with a spray bottle as you sand, and move in a consistent pattern to avoid unevenness.
- Polish the Headlight: After sanding, apply the polishing compound to a clean microfiber cloth or a polishing pad attached to an electric drill. Buff the headlight in a circular motion until it becomes clear.
- Apply UV Protective Coating: Once the headlight is polished, apply a UV sealant. This step is critical, as it protects the plastic from future yellowing and damage caused by UV rays.
Step 3: Polishing the Headlight
If your headlights only have light scratches, you might be able to skip sanding and go straight to polishing. Use a high-quality headlight polish and a microfiber cloth, working in small, circular motions. For deeper scratches, sanding first is necessary to remove the damaged layer.
Step 4: Applying a UV Protective Coating
After polishing, the headlight will be clear, but it’s vulnerable to UV damage. Apply a UV protective coating to seal the surface. This will help maintain the clarity of your headlights for a longer period.
Alternative Methods for Fixing Scratches
If you don’t have a headlight restoration kit, you can try some alternative methods using common household items.
Using Toothpaste as a Quick Fix
Toothpaste contains mild abrasives that can help polish out light scratches. Apply a small amount to a damp cloth and rub it into the headlight in circular motions. Rinse and repeat as necessary.
Baking Soda and Water Mixture
Mix baking soda with water to create a paste, and apply it to the headlight in a similar fashion to toothpaste. This method works for minor scratches and cloudiness.
Commercial Polishing Compounds
If you have a commercial car polish or rubbing compound on hand, these can also be effective. Use them with a microfiber cloth or a polishing pad attached to an electric drill for faster results.

Regular Cleaning to Prevent New Scratches
Wash your headlights regularly with soap and water to remove dirt and debris that could cause new scratches. Avoid using harsh chemicals that could damage the plastic.
Using Headlight Covers for Extra Protection
Consider investing in headlight covers or protective films. These add an extra layer of protection against scratches and UV damage, helping to keep your headlights clear for longer.
When to Replace Instead of Repair

In some cases, repair might not be enough, and replacing the headlight could be the better option.
Signs That Headlight Replacement is Necessary
If the headlights are severely scratched, cracked, or have internal damage, it might be more cost-effective to replace them. Also, if your headlights have been restored multiple times and continue to fade quickly, replacement might be the best solution.
Cost Considerations for Repair vs. Replacement
While restoring headlights is cheaper than replacing them, constantly needing to restore them can add up over time. Weigh the costs and benefits before deciding to repair or replace.
Conclusion
Fixing scratched headlights is a relatively simple process that can greatly improve your car’s appearance and your safety on the road. By following the steps outlined in this guide, you can restore your headlights to like-new condition and extend their lifespan. Remember, regular maintenance is key to keeping your headlights clear and functional.
