    So I finally installed my BHLM lights on the truck, and wouldn't you know it, the frickin' passenger side is fogging up!
    Please respond to my poll on the best step to take next.
    Thanks

    Removing, disassembling the headlight and reassembling with new sealant would be the best but also the most evasive. Just reheating and squeezing the headlight assembly most likely won't work. The issue is there probably wasn't enough sealant used in the first place so that would be a waste of time. If you're going to bake them, remove the lens, use 3M window weld and press them back together hot.

    If you can dry them out with a hair dryer and there are no water spots on the lens then just put some silicone around the perimeter of both headlights and hopefully that keeps the water out.

    I wouldn't drill a hole in the headlight assembly, it's already leaking, why give water more places to get in there?

    I forgot to mention in my original post, both headlights received a nice bead of silicone around the perimeter after they had cured...I can't figure out why just one is fogging; they both got the same treatment including all that extra sealant! damnit!

    So these aren't Ebay BHLM, these are OEM headlights that you did yourself?

    Check for leaks around where the bulbs plug in, make sure the vent caps on the back of the lights are all still there and secure. If you used extra sealant when you reassembled the headlight and put a bead of silicone around the perimeter, I'd guess you're not leaking from the perimeter but rather one of the bulb holes or one of the vent holes.

    yup...OEM lights I did myself. I did not add any sealant to the channel, just re-used the OEM sealant. Once I was done, I put silicone all around and pused it in to the perimeter. Really bummed that I have to take the darn thing apart again.

    It happened to mine the other day. I went wheeling all day, and then the engine bay was dirty, so i cleaned it out with super-clean and water like i have done my whole life,... well i guess some water got in from the back side and now it fogs up :/ What a crappy design Toyota :p

    Anyways, I am tiring to figure out how to fix the problem without taking everything apart, if i take it out, I am going to replace it with a new headlight assembly

    These retro kits are a real pain in the butt living where it rains 23/7

    well...finally had some warmer weather today, so I pulled the headlight, baked it and added window weld, baked again and used the clamps and ratchet strap idea... There was at least a 1/2 cup of water in the light!...its back on the truck now, so fingers crossed it works!
    While fixing this I had a thought...because of the fins on the fender well for air intake to the engine, I'll bet the passenger side light is more prone to leaking. I imagine that light gets pounded with rain water and wind more that the driver's side. I think people should take extra care on the passenger side when doing the BHLM mod.

    You can also stick some of those desicant packs in the light to help absorb moisture.

    I did the Land rover fix to the problem of condensation. Say what you want it works. Tubes draw in and exhaust air.

    Is that one tube connected? or two separate? I just did the BHLM today and i'm paranoid about moisture.

    So McDowell with the smiple venting via the tubes it can't prevent fogging, but once fogging/condensation occurs inside the light, the tubes open to air cause increased venting and then resolution of the condensation more quickly? Or are you saying that the tubes can actually Prevent fogging?
