Things you will need:
Clay Bar
About 20 minutes.
First read the instuctions on the clay bar product you have, but I highly doubt it will be different. This stuff is amazing seriously, used it all over the car and tested on headlights and amazingly it worked.
Start off with lightly misting the headlights with the water bottle and then gently rubbing the clay bar on the light and notice the texture goes from kinda chalkboardish to glass. As you progress press harder and harder and keep rubbing until satisfied. Works like a charm and is faster and not as risky as sanding!
This is the stuff I used
EDIT* Also found some stuff that works a little faster and better! Brasso $2.99 at Home Depot.
