I used 1500 grit sandpaper on the outside of the headlights. Really work it until all the little scratches are out of it. You can even go with a higher grit sandpaper ie 1800. Then clean headlight. Get a spray can of clearcoat, they can be bought at most hardware or auto stores. Use even light coats, to keep it from running. Usually you wil use 4-5 coats. Spray until you see a crystal gloss. The outcome is incredible, your lighting will be brighter and they look better thenbrand new.
