My tail light just starting fogging up yesterday about an hour after I washed my car. I was wondering if anyone else has had the same problem, and what you have done to solved it. I have a feeling its some kind of leak so I am going to seal the crap out of it, but how can I get the small amount of water and condensation that is already in the tail light?
Take your tail-light out of the car and set it in the sun with the lense facing downward (the part where the bulb goes in should face the sun) Leave it out for an hour or so, or until all the moisture is gone. Then go buy some clear silicone from Wal-Mart/Lowes, but make sure it's weather-proof.waterproof. Seal all around the edge of the tail-light, wipe off the excess, let it dry, then you're good to go.
