Somehow water has leaked into my driver's side headlight and tail light. I detactched the lamp cover on the headlight hoping it would air out, but this cold air isn't going to evaporate anything. Any advice or tips on how to dry these out?

 

1 - best, most expensive way: replace affected lamps

2 - cheap way: drill a small hole, 3/16" or so at the lowest point of the reflector

 

DONT DRILL A HOLE IN THEM!!!!!

if you have a issue with them getting water in them find out where it is and use a sealer to seal the hole up.
IF you just have condisation in them then you can send the wife to the store with some money why you steal her hair dryer long enough to get the water out of the head lights etc...
most folks have this after the cars get older and they have had to change out the bulbs. and the gasket is forgotten or is gone. you can order a new one threw the dealer or you can find some thin rubber and make your own. all the are is a small thin gasket to help prevent water getting in them .

BUT DONT DRILL THEM!! you will have this issue everythign it rains or you wash your car.

 

yes, dont drill them, then you'll get more condesation, even if its in the bottom.

but like mickey said there is a gasket around all the bulbs on the vehicle and its designed to keep water or condesation out, if you dont feel like going to get a gasket or rubber o-ring then use a little silicone around the bulb when you but it in that should help.

 

TIME TO CHANGE THE BLINKER FLUID!!!! =D

I would agree that it is a gasket problem. I would just get some clear window sealant or caulk and put a light coating on the gasket (inside and out) and replace them. See what happens but consider ordering some new ones.

 

well ok, just buy new ones. if your missing a gasket, sure replace that and just get the water out. as far as resealing... let me know of your success, especially long term. i dont think i could seal better than factory, and as far as i know anytime it happens under warranty they always get replaced.
