I had the exact same problem on my truck. I pulled the headlight and drilled a very very small hole in the front bottom corner (what I felt was the lowest point). You cant see it, and it did help the problem, though it still gets foggy sometimes..... I will likely do the oven trick soon and black mine out, and the seal the whole dang thing so tight nothing will get in it.

to answer your question though....yes you can drill it ....but its probably not going to accomplish exactly what you want it to.

I don't think the problem is water getting in...

I honestly think it's a venting problem.

It's not a venting problem. Study a stock headlight, and you will not find any venting port or hole. Drilling a hole in a corner will help you drain the water, but I promise you the headlight will fog (ask me how I know), because the inner temps of the headlight will differ from the outer headlight surface. After you drill the hole and get the lens completely dry, re-seal the hole you drilled with some clear silicone.
I used a hair drier placed by the headlight bulb hole (headlight bulb removed) to dry out any miniscule water vapors after draining.

This is a common problem with the cheaper aftermarket headlight assemblies. If you pay $100.00 or less for a set, they are the cheaper ones. Like mentioned above, they can be made to work by heating them up, removing the clear lense, clean out the old seal in the groove, then resealing them.

But if you choose to leave a hole in the lense to drain water out because of the "less than atiquate" sealing of the cheaper units, they will eventually start to fog up.
