if you go to discount auto parts buy a bottle of Meguiar's PlastiX, it's a black bottle with a red X on it. buy yourself a terry towel or a polishing sponge. apply as much of that PlastiX as you need and start rubbing at the lamp housing in a circular motion. i gurantee you almost 98% of HAN users will agree with me this product should remove any blemishes or scratches from your headlamps.
