Headlight Restoration: Why Your Headlights Turn Yellow

Cloudy, yellowed headlights make a car look old — and more importantly, they cut how far you can see at night. Here's why it happens and how to fix it.

Why headlights turn yellow

Modern headlights are polycarbonate plastic with a protective coating. Over time, UV rays and weather break that coating down, and the plastic underneath oxidizes into a yellow, hazy film. It's not dirt — it's surface damage.

The safety problem

Foggy lenses scatter your headlight beam instead of projecting it, noticeably reducing how far you can see at night. On dark Long Island back roads, that's a real safety issue, not just a cosmetic one.

How restoration works

Headlight restoration wet-sands away the oxidized layer in stages, polishes the lens back to clarity, and applies a fresh protective sealant to slow the fogging from returning. The difference is dramatic — and it takes about an hour.

Restore, don't replace

New headlight units are expensive. Restoration brings back the clarity for a small fraction of the cost, and it improves your night visibility right away. It's often added onto a detail while we're there. Book it and we'll come to you.
