    This is how Range Rover deals with light condensation. The 2 tubes you see on the back of the lights are holes in the housing. One hole on the bottom lets in air and the hole on the top exhaust the air and condensation out. Tubes are connected for off road use and water will not flood in. This will help anyone who has done the BHLM having issues. It helped me.

    thats a good idea but, who is going to remember to connect their headlight hoses when they go off road or when it rains for 5 days lol.

    the 2nd gens have vent on them as well same principle one on the bottom and one on the top although i don't think they are nearly this open to the elements.

    intake when i took off my factory stuff it was lower than i thought it was i'm so happy i have the snorkel now.

    headlight breather mod might be a good idea though actually not kidding a one way valve like our diffs have.

    It would be effective if you could have one hose up and out of the water (or somewhere sucking dry air) and one connected to a vacuum. That would eliminate water build up entirely, almost like a mini defroster for your headlights.

    I don't have any more of those breathers... My fog light housings are sealed up tighter than a termites butt hole :cool:

    Screw headlight breather mods, if you seal the lights correctly, you shouldn't have condensation issues. Maybe if you submarine your truck constantly enough and keep getting water in them, then run run a hose from the breather holes to the inside of the cab or seal them up permanently.

    Condensation without any off roading or rain... just started on my passenger headlight only. Running highbeams in the day drys it, but it condensates again the next morning. Never happened before on this 2010 or my 2005..?

    I am somewhat confused about this issue.

    My headlights have some condensation post BHLM. Not often or terrible, but it is there. I was going to reseal them. But looking at the back there are definitely open vents. So how can it really matter that I left a pin hole somewhere that allows humid air in and out. If I seal that I will still have much more area for air to flow in/out in back...

    I don't know what a BHLM is, but these are halogen lights, not sealed beam, so they might need an open vent to not condensate? Perhaps the vent on my passenger side lamp is clogged? Photos of where this vent is would be great...

    Found a black rubber cap (with a white round sticker) covering a hole into the back of the headlamp housing. Inside the rubber cap is a filter... I could not detect any clog, dirt or reason why the one lamp gets filled with condensation... but I removed the plug and will check the light tomorrow.

    I did not see anything different top and bottom?
