Headlights on my '12 Jetta were getting a little cloudy (nothing crazy - just a slight haze) so today decided to try some Meguires Scratch X 2.0 on them after a car wash because I had it out to remove some very fine scratches on the body.
Color me impressed - except for a bunch of very small road rash chips the clarity went to pretty much brand new with no notable haze. Only downside now is while the Scratch X bottle does not indicate wax is needed afterwards, it appears some online forums recommend it as the Scratch X is not a wax product in itself - and unfortunately I don't have any wax in house currently so going to have to make a run to the auto store to get some wax.
Now I don't know how this would work on severely yellowed/crazed lenses as mine was in the beginning stages of cloudiness so your results may vary.
