I cleared my headlights last weekend and I washed it about an hour afterwards. Left the car outside and the weather was a bit chilly.
To make the story short, I found some condensation on the part where the diffuser used to be. It dried up couple of days ago though. Do I need to take apart and reseal or has it seal and now the moisture is gone.
Please help.

 

How well did you reseal it? If you resealed it well, you shouldn't need to take it apart to reseal it.

 

Resealed with silicone pretty well. Do I just need to reheated?

 

Did you heat the cleared diffusers that you put in under hot water so that they fit better? You may not have dried the fully if you did and it was coincidence that the condensation showed up after you washed your car.

 

I think he went with the no diffuser look. Probably best to take it out and reseal it. I had the same problem, but my problem didn't show up till the weather changed. Reheat, make sure the tabs click together, and add silicone sealant.

 

if u don't feel like reheating/sealing, tie some string around a small dessicant bag (very securely) and pop it into one of the bulb openings (remove bulb of course). tape up opening, leaving string accessible.

let sit overnite - then pull string and dessicant bag out, immediately replace bulb. that should remove most all of the moisture in the headlite.

 

try this... run water onto and over the headlight for an extended period of time.

if condensation returns -- you've got to deal with resealing issues... if not, you're good to go for a while...

i ended up w/ a honest to goodness leaking issue from resealing, but it was come and go for a while before i finally broke down and pulled the headlight again... when i did, i found over a cup of water in it... i'm not sure how it was 'come and go', but... don't wait too long, find out asap.

the easiest way i found to dry out the light was to pull the bumper and light casing again, drain the casing and inspect everything, touching up where needed. then, set a hairdryer on medium heat full speed fan to blow into the highbeam socket, allowing the air to come out of the turn signal and running light sockets. leave that for about an hour (checking often). it will make the whole light nice and warm, and the glue gets gooey again. press the light together allowing it to cool after you've plugged the holes. once cool, then reinstall the lights, casing, bumper, etc..

 

I will try the blowerdryer trick.
Thanks everyone for the input.
