Water in Headlight
I have about 3/8 inch water in the passenger side headlight. It has always stayed condensed over on the lens. Been meanin to clean it out for many years. Well, today I pulled the battery, the battery box and the surrounding trim ring in an effort to remove the headlight lens. I now have the lens exposed. Just not sure how to actually remove the lens. Do you turn the plastic clips on the lens back 1/4 turn to release the adjusting rods.
I am not sure how the water got in the lens in the first place. The o-ring around the bulb seems good. I find it hard to believe water entered around that o-ring. Perhaps the lens leaks around the seam at the lens edge?
After all the work just to get to the lens, I am now thinking of just drilling a drain hole in the bottom corner of the lens. Anybody tried that?

The headlight assembly should already be vented to the outside. I suspect that if the water is 3/8 inch high-a 1/16 drilled hole at the bottom of the reflector would release the water and could be sealed with sealer afterwards. I would just worry about debris getting into the headlight assembly from the drill bit.

I just drilled mine- 1/8th inch hole on the bottom to drain the water. I've been keeping the headlights on while driving to dry up the rest of the condensation- getting better but not finished yet. I may just silicone up the hole when done, or leave is to allow the condensation to vent in the future.

Haven't had rain here in over a month. Truck is under carport and the bulb is removed for a week to air out. I tried to blow as much water out as I could with a long air gun. Still a good amount inside. I was going to hit it with a hairdryer next, but it has been raining steady the last three days. I will seal the lens seam. I suspected that is how the water is getting in. As a last resort I will try the drill trick. Thanks for the feedback!
