I had a broken tail light and no luck finding a good one at a junk yard. Decided to fix it by making a new lens. I ran across this and ran with it. http://www.6gc.net/howto/make_clear_tail_lights It's illegal to have clear lenses and also illegal to have colored tail light bulbs. Heres how I did it but with patience you could make it look good.
