Well it seems I have become pretty good at refinishing headlights, but I have a question that would save alot of time. How necessary are the little nubbies on the outside of halogen headlights? It seems to me they are for aiming the lights but I'm not sure. If I sanded them off with a dremel and sanded the headlight smooth what would this do? It would really save alot of time and I think it would make the lights look alot better... Any thoughts?
