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.
