    I noticed lately that my passenger side fog light has condensation and a bit of water in it
    What can cause this?

    I had the truck washed today before I went to pick up my replacement DVD player and didn't notice it till I got home and seen it I thought it might have got in there at the wash

    I removed the bulb (which is a hid) to make sure there was no water on it before I turned them on to let the bulb heat the housing up In hopes of it drying out the housing but no luck

    I am going to see if the warranty is good to see if I can get a replacement if not I will just buy a new one

    Not uncommon. I had to replace both of mine due to the lens coming apart from the housing. I paid like 60 for a pair.

    Is this caused by my hid bulbs or not(I doubt it though as both would be doing it)

    No more than likely the seal on the cover is failing allowing moisture in. Eventually it can fill with water and blow a bulb.

    Before replacing it, I'd try removing it, taking out the bulb, and drying it out with a hairdryer. Then put a bead of silicone around where the lens is bonded to the housing.

    Not good considering how these hid bulbs shatter

    Ok I will try that as soon as the rain lets up

    It didn't seem to be coming from the lens area but the bulb area but I will take the extra precaution and put some silicone around the lens

    Thats what I did, hell of alot better than spending $$ on replacement fog lamp assemblies.

    *NOTE* Use clear silicone to adhere lens to fog lamp housing. I had some black RTV laying around the first time, and it kinda gooed into the housing. I had to remove the lens and reseal with clear silicone and looks just like new.

    Did you give this a try? I got a brand spanking new pair of TYC fog lights. After the first rain they were in, there was mad condensation on the inside. I would hate to go through the hassle of buying another pair when I could get this resolved. I too have 880 HID bulbs as well. Should I just run some clear silicone on the outside or do i need to take the fog lights off and run some water in it to check for leakage?

    I ended up not needing to as there was dirt on the bulb base I cleaned it and haven't had this happen since
