Clean A Dull Headlight Lens

Polycarbonate headlight covers fade with age and sunlight exposure.

Your vehicle headlights light up your way when driving at night or in poor weather conditions. Covering the vehicle headlights are polycarbonate lenses that protect them from damage. During use, sunlight, age and road debris cause the lenses to yellow. This reduces the distance your headlights project light. Polishing years of fading from your polycarbonate lenses increases the safety of your vehicle.

2. Secure a buffing wheel drill attachment into the chuck of a drill motor. Fasten a buffing pad to the end of the buffing wheel attachment.

3. Apply plastic polish to the buffing pad. Buff the surface of each headlight until each has an even coating.
