Headlight crazing, the formation of tiny cracks on the plastic lens of your car’s headlights, is a common problem that can impair visibility and reduce the effectiveness of your headlights. While headlight crazing cannot be completely eliminated, there are several methods that can help restore clarity and improve the functionality of your headlights.
Causes of Headlight Crazing
Headlight crazing is typically caused by prolonged exposure to sunlight and ultraviolet (UV) radiation, which can break down the plastic material over time. Other factors that contribute to crazing include:
- Heat from the headlights themselves
- Chemicals used in car washes
- Road debris and sand
- Oxidation
How to Fix Headlight Crazing
1. Wet Sanding and Polishing
This method involves using a series of progressively finer grits of sandpaper to remove the damaged layer of plastic, followed by polishing to restore a smooth surface.
2. Clear Coat Application
Applying a clear coat sealant to the headlights can help protect them from further damage and restore some clarity.
3. DIY Headlight Restoration Kits
These kits typically include a sanding block, polishing compound, and clear coat, providing an affordable way to restore your headlights.
4. Professional Headlight Restoration
Professional headlight restoration services offer a more thorough and long-lasting solution, using specialized equipment and techniques to remove crazing and restore headlight clarity.
Precautions and Tips
- Always use a soft cloth or sponge when cleaning your headlights.
- Avoid using harsh chemicals or abrasive cleaners.

When to Replace Headlights
If the crazing is severe and cannot be restored through repair methods, it may be necessary to replace your headlights. This is especially important if the crazing is affecting visibility and safety.
Alternatives to Headlight Repair
1. Headlight Restoration Film
A transparent film can be applied over the headlights to protect them from damage and restore clarity.
2. Headlight Bulbs with Brighter Output
Upgrading to brighter headlight bulbs can compensate for reduced visibility caused by crazing.
