Moisture in headlight lens?

2016 TRD PRo, stock headlights. Right lens has some condensation inside it - do I need to replace the assembly? (left side is dry).

 

My cheap aftermarket housings on my 4th gen started to have condensation about a month after I bought them. Problem has persisted for a couple years now. It's not a death sentence but is irritating to say the least. I even took a 1/64 drill bit and drilled some drain holes in the bottom of the lenses lol.

I deal with it for now because quality housings are stupid expensive for this thing. Don't have the problem on my 5th gen so I haven't priced them.

You could take the housing out, remove the bulbs and dry it out. You can stick it in the oven at a low temp for awhile and crack it open, then clean and reseal. Or you can try to silicone up the possible trouble spots without doing the surgery. There are threads out there explaining how to do the surgery, but I was never motivated enough to mess with it.

Also, unless there has been some developments, aftermarket for any headlight housing is a hit and miss prospect. Some people swear by the cheap ones, and others have the same luck I did. The reflectors and projectors in the cheap ones are a hit and miss situation as well. Most quality housings are several hundred dollars. OEM replacement might be the best option. But like I say, you can drill a small drain hole and deal with it for awhile.

Hopefully someone with 5th gen experience will chime in here soon. Good luck!
