Leak in headlight

Keep getting condensation buildup inside my right light assembly... Anyone have experience with sealing up a headlight?

 

did you recently do a BHLM or retro where you had to take the lens off?

 

Just bought the truck so theres a very likely change the previous owner did, especially considering there are what appear to be aftermarket HID lamps of which the left just died on me yesterday.

 

From what I have gathered over time reading here... Best plan of attack would be to first check all the seals on the headlight. Light bulb, corner light, and turning light. might even help to add some sort of lubricant to them (rubber "o" rings) to make sure its a good seal.

If this doesn't fix it a lot of guys will re-seal the outer lens where it meets the body of the headlight with a sealant. Again, from what I have read silicone is a water based sealant so if at all possible use a latex based sealant.

Hope this helps a little.

 

First thing I would check is to make sure the bulb is seated properly.

 

Just curious... How would an unseated bulb cause condensation in the headlight?

 

rain. hummidity. rat piss.

I am speaking from experience, though. When I first bought my truck it had blue-ish bulbs, and a condensation in the headlight issue. I found that whoever changed out the bulbs last didn't put it in correctly which did not form the seal. Moisture got in.

 

ALL modern day headlights are vented to atmosphere. This is to prevent the lens from popping out as the inside air heats up with the light bulb. DO NOT EVER totally seal up a headlight. What does happen sometimes is that on humid days, as the headlight cools, it can draw in moisture through the vents. If you look at the picture below, you will see them. One is the lower left of the picture, and has a white sticker on it. The other is the upper right of the picture, and is black. If either of these are missing, cracked, or broken, they can allow excessive moisture in that lens. So I would check those when you get a chance.
