Yeah not one of there better thoughts. Seems the radiator's heat also warms-up everything up front including the headlight housings and when they get splashed with cold water the air contracts and draws air in through the tubes....like it's supposed to...except if there is steam around the ends of the vents, that gets pulled in too. Of course there are some with bad seals but try this first. You can pull the lights out for a while to dry them out..maybe use a hear dryer..just don't drive it that way otherwise dirt will get in.
