How to Prevent Headlights from Getting Foggy

If by foggy you mean the plastic is no longer clear due to age, you can't do anything to prevent that. The plastic headlamp housings made from Lexan are subject to deterioration from UV light from the sun. To slow this process, ensure that the vehicle is garaged when not in use and washed regularly with UV-protectant wax.

Solutions for Foggy Headlights

Those headlight restoration kits work pretty well if you enjoy a do-it-yourself project. However, if you want a more guaranteed solution, consider using UV protection products specifically designed for automotive headlamps. These provide a buffer against UV damage and oxidation, delaying the fogging process.

Steps to Prevent Foggy Headlights

1. Ensure Tight Seating of Rear Boot: Whenever you change the headlight bulb, make sure the rear boot on the cap is always seated tightly. This helps prevent moisture from entering the beam. 2. Avoid Ingress of Moisture: During car washes, avoid pouring water on the headlamp assembly. Also, be cautious not to damage the front glass, as this can allow moisture to enter the beam. 3. Apply Surface Protectants: Use a plastic protectant to shield the headlight from UV damage and oxidation. This protectant also acts as a buffer against road debris. 4. Regularly Wash and Wax: Keep your car regularly washed with UV-protectant wax, especially if you can't keep it in a garage. This can help slow the progression of plastic deterioration.

Effective Headlight Protection Kits

Several kits and products are available in the market, but my experience working at an aftermarket auto parts store and interacting with auto repair shops as a delivery driver has shown that the more expensive kits work more effectively. These kits often provide detailed instructions that need to be followed exactly for optimal results, which can be both tedious and time-consuming.

Application of UV Protectant

Apply a rub-on UV protectant spray every few months. This is crucial as UV light is what clouds the plastic. There are also online companies that make clear headlight UV plastic vinyl covers that can fit your car model, providing an additional layer of protection against UV rays.

Conclusion

By following these steps and using the right products, you can significantly reduce the fogging of your headlights, ensuring better visibility and safety on the road. Remember, the key to combating foggy headlights lies in preventing moisture and UV damage, and regular maintenance is crucial.
