Pitting from like sand or salt and I haven't tried anything yet thought I would try for some opinions first, I thought about using toothpaste but it's not faded it has tiny chips out of the clear lense cover. So I was thinking of maybe sanding it and buffing but I don't know.

Hope th is clears it up a little bit

I've used the Mother's headlights restoring kit before. It takes some elbow greese with the little wet sanding pads they supply in the kit but the results looked good. I've also used it to shave the raised plastic lettering found on some automotive reflectors, which no one really notices so I'm not too sure was worth the time.

It's a little uneasy when you start with the rougher pads as the plastic turns white & you think you've just destroyed your lights but keep following the direction and it turns out well.
