Never use fine sand paper...EVER, if you lens are foggy but not yellow, You will remove the uv protection from the factory and eventually have to replace them. For improvement but not 100% better result, and basically free. Use toothpaste. Otherwise use a plastic cleaner if they are plastic. They sell some stuff called Pittman's Headlight cleaner, Takes about 15-30 seconds and will clean them very well, almost like new, unless your uv protection is already gone. Just don't wet sand or sand your headlights period! They look better but will turn yellow quickly and look worse than they already are. Even if you use a clear coat afterward. Those are the cheapest and best way to clean them outside of buying new ones.

My headlights had a yellowish foggy haze to them. My hubby went to the autoparts store and found some headlight cleaner and now they look 100% better. You may want to try that before buying new headlights.

If it's plastic headlamps, you have to replace the housing. If it's the glass sealed beams just buy a new light. There's no cheap way to clean them that we've ever found.
