Faded plastic headlights don't look good from inside or outside the vehicle. On the outside, it detracts from the vehicle's appearance--making it look worn. From the inside, it can affect brightness when it's needed the most--at nightfall. Rather than replacing your old headlights with new ones, which would be more expensive, do this simple repair at home.
- Skill level:
Things you need
- 1 piece each of 800-, 1,500- and 2,500-grit sandpaper
- Soft, clean cloth
- UV inhibitor coating/protectant
Soak one piece each of 800-, 1,500- and 2,500-grit sandpaper in water for about 10 minutes.
Use the 800-grit sandpaper first and gently rub the entire lens, making sure to keep the lens wet while sanding.
Use the 1,500- and 2,500-grit sandpaper in the same manor.
Dry the lenses with a clean, dry, soft cloth.
Apply UV inhibitor coating/protectant purchased from any local auto shop by allowing it to sit on a clean cloth for several minutes before wiping it gently onto the lenses. Wipe slowly up and down the lens and don't double back or wipe back and forth. The coating hardens quickly and can make a mess.
Apply the second coat of UV inhibitor coating/protectant after 24 hours.
Tips and warnings
- Avoid direct sunlight while sealing the lenses.
