Guys, I think you are approaching this from the wrong angle. I had a major water problem in my tail lights as well and solved it without spending a cent and works like a charm (got the idea from a reputable body shop manager).
Take out the tail lights and take a small drill bit and drill small holes on the bottom (and make sure it is the bottom) of the housing. You can let the moisture dry out, but don't have to. Replace the housings back onto the car and turn on the lights. The heat from the lights will evaporate the moisture and the new holes you put in the bottom of the housing will act like drain holes and/or allow the vapor to escape. It doesn't cause any harm to your lights or wiring. These lights don't need to be sealed. Try it out for yourself and you'll see that you will never have a moisture problem again.
ive heard of doing this too, but i never knew exactly how small of a bit to use, or exactly where to drill it.
