I've seen the light!
The headlight lenses on my 2002 VW Passat were so clouded over that they looked like they were spray painted beige. Headlight cleaners did nothing. Like anything VW it was a bit of a pain to install... had to take off the grill, and then the bumper, and then this little sub-bumper... and of course they don't make it easy to reach those rear screws.. had to remove some kind of air filter intake hose to get at one. Anyway, keep track and put it all back together the way it came apart and you're good. Now my only problem is the lights look so great the rest of the car looks kind of shabby by comparison!
