I have searched for a cure for yellow headlights for sometime and nothing has seemed to work too well on my truck. Tried the Mr. Clean pads, did the aluminum mag wheel polish, nothing got it to where I wanted it at, plus I am really anal when it comes to stuff being perfect, especially with my truck. The other day when I was at Napa, I picked up "5 minute Headlamp Lenses Restorer" and boy does it work. It is the best $10 I have ever spent on the truck. Comes with 6 pads that go onto a plastic base that goes into a drill. I sprayed it with water and just let the pad do its magic, and it worked very well. You could actually see all the junk caked on the light collect on the bumper. The lights look like they are brand new. Looks especially well with the clear side lights I have on the truck. I havent driven it in the dark yet, but I am sure it will help, my low beam visibility was getting pretty crummy. Just wanted to share a positive experience with a product, hoepfully it will help somebody out.
