Crappy yellow headlights

Hey I was wondering if any one could help me. I have a 96' ram and the headlights will not let any light through so I can actually see at night. Is there any way to clean them so the light will shine through? If not what else can I do?

i think i heard bleach works but im not positive on that one

There's been some discussion on this in other forums. Flitz plastic polish, or other plastic cleaners were thought to work, but alot of folks just sprung for the new lenses, although they're $$$. Using the windshield cleaners at your local gas-n-go on the headlight lenses will help get them yellow, because some people use those to take the gas off their vehicle after they spill it, and the gas eats the plastic. Good luck with it, I'd be interested to hear if the polishes do any good.
