What Is Uv Damage To Headlights?

If you’re wondering why your headlights are cloudy, hazy, or yellowed, the answer may be UV damage. Ultraviolet (UV) rays from the sun can cause serious damage to your car’s headlights over time, leading to reduced visibility and a less attractive appearance.

But what exactly is UV damage to headlights, and what can you do to prevent and repair it?
