I had one headlight that for some reason was collecting water. Well headlights are a pita to get out on these trucks so I just ran it and figured I'll fix it when something breaks. One night the water hit the bulb and it was toast. Well to drain it I drilled a small hole in the bottom of the headlight. The water drained out, and now there is never condensation buildup in that headlight. So just drilling a small hole may be an easy way to get rid of that buildup if you have it like I did. Figured I'd post in case others get tired of seeing water all over the inside of their headlights too
