Before and after headlight restoration showing yellow hazy lens restored to clear

Why headlights turn yellow and hazy (and what actually fixes it)

Factory UV protection fails over time. Polishing alone cannot replace it. Here is what drivers in Belgium and across Europe should know.

If your headlights looked clear when the car was new but now glow yellow or scatter light at night, the problem is usually not dirt. Modern headlights are made from polycarbonate plastic with a factory UV hard coat. Sun, road grit, and years of heat cycling break that coat down. Once it fails, the plastic itself oxidizes.

A quick buff or DIY kit can make lenses look better for a few weeks. It removes surface haze but leaves the underlying plastic unprotected. Without a new UV hard coat, yellowing returns fast, especially on cars parked outside in Belgian and European climates.

What professional restoration changes

  • The failed factory UV layer is stripped completely, not polished over.
  • The lens is refined to a smooth, coating-ready finish.
  • An OEM-grade UV hard coat replaces the protection the lens lost.
  • The coating is hardened in-shop before handover, so you can drive home immediately.

At SHINES, we follow that full sequence on every restoration. Fixed pricing starts from € 149,00 for both headlights. Book online or read our process overview to see what happens when you visit our garage in Ingelmunster, Belgium.
