Mine were pretty faded when I bought the VX over a year ago, and I just now got around to restoring them. I bought Meguiars Heavy Duty Headlight Restoration Kit from Walmart for under $30. It comes with 1000 grit sanding pad, 3000 grit sanding pad, a polishing compound, drill mounted buffing wheel, and a sealer/protector to finish the job. They look amazing. A friend of mine actually assumed I bought new lights. The kit cam with enough compound to do multiple vehicle, I think I can even stretch it out enough to do three vehicles. About 20 min. per light, and amazing results. Highly recommend you consider this even if yours are really cloudy and cracking.
