Last couple days have been snowy here, not real bad, BUT I have found that each day on a 20-30 mile drive after dark, I have to stop about halfway and find a gas station to use the squeegee to clean off my headlights so I can see again. The salt and road gunk builds up on them to the point where the low beams are useless and the high beams throw about as far as the low beams normally do.
I was thinking maybe wax, silicone spray, or rain-x? I know there's dressings you can get for wheels that supposedly make dirt hose right off, but it would seem that it would be far more useful to have something like that for plastic-lensed headlights?
I don't remember this being such an issue in years past, but this is the first time I've really been in snow in current car ('08 Impala.) Maybe a quirk of the aerodynamics of this car? Last personal car (Porsche
944) had hidden headlights which at least kept them from getting (too) dirty when not in use.nate
