moisture inside head light lens

I noticed the other day that I've been getting a lot of moisture inside my driver side lens, wondering if this broken black plastic piece is the reason, I haven't seen any other cracks. Not sure how I would fix this. Any thoughts?

 

Check to make sure all of your bulbs are secure in the slots. Are those still the factory headlights housings?

 

That piece isn’t part of the headlight.

 

I believe they are factory headlight housings, I bought the truck used a year ago so I have to check with the dealership. So the black broken piece has nothing to do with sealing the lens?

 

Drill small holes in the bottom face.
Problem solved.

 

We have a winner! Did this on a previous vehicle and it worked great. You only need two (roughly 1/8”) holes per headlight.

 

Silica gel packs, don’t drill holes!

 

Best way is to remove all bulbs and use a blow dryer to dry the inside (easier out of vehicle but can de done in). Check the main bulb big rubber seal. Check the vents if open plastic tube type they always will get water in (some aftermarket have them) so don't waste your time replace them and lots of posts on what to get and checkout headlight depot. Silicon seal the seams after dry. Yes check for exterior cracks.
If you drill any holes they cannot be where oncoming rain water will be forced back up into them at 70 mph - I never drilled mine but replaced. But if they are getting old why not drill before forced to replace as a stopgap.

 

so do I need to take the housing off to drill holes? Or just drill on the outside towards the bottom of the housing?

 

Looks like it’s bad water damage inside of it. Just replace the lights.

 

If that were the solution, I think the factory would have done it. What you are proposing is a "fix" to a problem that should not happen in the first place. Moisture inside an OEM headlight housing is a sign of a leak that wasn't there to begin with. As others have said, check to make sure the bulbs are seated properly. If they're not, that's how the water got in. If so, use any of the methods others have suggested (other than drilling holes) to get the moisture out.

BTW, holes are just as likely to let water in as they are to let it drain out.

 

I just drilled holes in the lower face of the housing with-out removing the lights.
The lights are aftermarket replacements... not an OEM headlight.
They crack when closing the hood I suppose.
They ain't cracked on the bottom side.

 

I can pretty much guarantee that during your next drive in the rain, water will be forced into the housings.

 

Remove light assy and drill hole in bottom. Blow out with dry air. Keep lights on to dry out.
