I just put in new headlights on my truck about 3 months ago and the low beam bulb keep breaking now. There is moisture in the headlight and was wondering if that would be the problem and if it is how do i keep the moisture out?

Nothing wrong with forced air drying like the video but on a dry day, it might only require bulb removal & a shop vac. Before I removed the headlight assembly, I think I'd take the chance of re-sealing all available seals. Sheila's Subaru the OEM bulbs lasted for years... yet the replacements had about 6 month bulb life on the H1 bulbs it took. Local auto parts just kept selling me bulbs... the same crappy bulbs... I found there ARE long light H1s made & ordered through NAPA... ALTROM ATR64150. I ordered a few but I didn't really get to test the longevity because the head gasket job failed & the shop would not stand behind their work... CPM Auto in Coventry, RI... claimed a cracked head. WELL, she gave the car to her sister whose BF runs a machine shop... trailered the car to Maine. Arse H*le shop hadn't planed the heads. Sister has driven the back several times over the last 2 years. I'd look at what bulbs you buy & buy a brand name with a life expectancy rating. Seems to me that bulbs are sold only by price. Some of the "bright' bulbs have much less life expectancy which I factor in.

I would do like Flagman says... I would either fix the current headlight case to prevent water leakage or just replace with a junkyard headlight. Then I when out and bought a set of Silver Stars and they are lasting a long time.

well I think i found out how to keep moisture out now and i tryed a small hole on the bottom side just to let it breath better and the moisture has been going away now and it only has been a couple of days so im going to try that and if i have to seal that hole up it will be easy to do it. thanks for the help guys

i had this issue with water being forced into mine and sloshing breaking bulbs. i drilled a small hole in the bottom but eventually the lens yellowed and looked like crap now i got projector unit replacements and hid. i can see!!!

well i tried doing the silicon around the headlights last week and seems to be keeping moisture out but not as good as i thought. Maybe i missed a spot but i took my time when putting it on and letting it dry. where did you buy your headlight and HID from and what did you pay? I might be thinking of getting them if bulbs keep braking on me.

Are the O-rings on the sockets still on or intact? If they are missing or damaged moisture could be getting in there.
