Moisture in the head/taillights

I'm debating drilling holes in my tail light assembly - I have a ton of water sloshing one of mine from when it was raining really heavy (like the worst rainstorm of the year). Other than that I get a few drops of water in one of them, but they function fine otherwise. I don't see a vent on these, but I do see that the water runs from the trunk opening and down onto my lights and that there is a plastic flap above the lights and that is broken a bit, but it doesn't look like it's anything but a wing to direct water so I don't see how it is leaking.

I took the lights off and blew compressed air into them after I got all I could out by turning them upside down and shaking them, then let them dry in the garage for a few days, but I'd like to prevent more water from coming in and I'm concerned that drilling holes will let dirt and salt in (I live in MN and they salt these roads a lot).

Drunkie, are you saying to bake them in the oven? Not understanding what you are saying when you say to press on the light and such.

Yes, they can be baked in the oven, from what I understand. I have also heard of using a heat gun on the edges. I'm not sure a hairdryer will get hot enough, but might be safer if so.

I'm not sold yet on drilling a hole in the headlights and would NOT drill a hole in the tail llights, especially if you're in a salted state. A good seal is the goal, here. I think drilling a hole is a bandage over the real problem, although would probably be fine as a last resort. The headlights in my trucks have never been drilled and they're all dry as a bone. The oldest is the original in my wife's '94 Suburban.

well, let's put it this way. the only way they get water in them right now is because they are already leaking. condensation is also a form of leaking. adding a 'vent' hole to the bottom to make sure they drain and breathe will not cause any ill effects, but in turn let them stay clear and dry.

the only other thing you can do is dry them out really good and seal them back up. however, when you do this and then condensation forms, its there to stay since you just sealed the light completely. drilling a hole isnt a bandaid fix, its a permanent one. living in the salt belt would not concern me about having another hole in the light assembly at all.

I can actually see the water pooring in my tail lights.. now obviously there is condensation.. I was headed to the junk yard to see if ican pick a set up.. but can I just seal it? Let me know..quickly..
