If your headlights are foggy, they may need a clean to avoid possible hazards. Just grab a tube of toothpaste from your bathroom, slather it all over the headlight lens, buff it with a cloth and rinse it with water.
If your headlights are foggy, they may need a clean to avoid possible hazards, especially if you drive often after dark or in foggy conditions. When those headlights get oxidised, the plastic lenses take on a dull or fogged over look which indicates that they need a good cleaning. This task does not require costly commercial products; just grab a bottle of toothpaste from your bathroom, slather it all over the headlight lens, buff it with a cloth and rinse it with water.
