Yellow, cloudy headlights don't just make your car look old. They can also reduce how much light reaches the road at night. The good news? You may not need an expensive detailing job to restore them. Here's a simple DIY method: 1. Tape off the paint around the headlights. 2. Wet-sand the surface with 2000-grit, then 3000-grit sandpaper. Start with a coarser grit if the oxidation is severe. 3. Keep the surface wet while sanding. 4. Buff with a plastic polishing compound. 5. Apply a UV-resistant headlight coating to protect the restored surface. That last step matters. Without proper UV protection, the yellow haze can return within months. Have you tried a headlight restoration kit? Did it last, or did your headlights turn yellow again?
