Hey guys this is my first post on HT. I DIY blackhoused my factory headlights but they quickly fogged up... without taking the stupid things off my car and resealing them, are there any techniques to drying them while keeping them on the car?

 

Turn the headlights on and it will heat up the plastic and help get rid of the fogging. You might be able to find a small hole and blow dry it as well. Either way, without taking the headlights off, there will be water spots from drying and you might not get all of the condensation off of the plastic.

 

Pop a bulb out and squeeze a couple Silica packets in there. They're designed to soak moisture.

 

You probably missing a TINY section when u resealed the lights, and therefore let some moisture it. I would try what matt said, but if that fails to work you will probably have to take them apart and redo it

 

you can drill small holes at the bottom of the headlights... did it on my buddy's integ, works like a charm

agree strongly. works like a carm

 

Take the headlights off put them in the oven. They will turn foggy cause all the water is evaorapting and they will turn clear when all the water is gone, thats how you know you have no water or condensation in there, then reseal again and wipe off the excess.

He mentioned that he didn't want to take his headlights off the car.

If you buy some fresh silica packets, it definitely should. Their design is to soak up moisture.

 

they only work for so long though so it isnt a perm. fix

 

i had this problem when i had to replace a driver side bulb

fogging went away but left **** all over the inside.

take em apart clean em re-sell em with twice as much silicone as before, works fine
