Condensation in headlight

[danmp]

Hello, I changed my bulb in my quad lamp for hid, since I have a little bit of condensation in . I changed my bulb on a cold Snowy day. What it can be the cause of this problem. The temperature that day or my hole in the cap ? I don't have too much condensation ( 1-2 square inches) and I got always the same amount of condensation , and always near the high-beam.

Perhaps the light you installed did not seat / seal properly when installed.
Try removing the bulb and inspecting the gasket to see if it was uniformly flattened.

Sometimes it helps to run a thin film of silicon (NOT GASKET SEALER) just generic silicon lubricant around the seal. Should help it slide around and not crimp up.

Also, sometimes vehicles just have bum lights that have a leak in em. Did you notice the issue ever with the factory light bulbs?

No I never noticed this with the oem bulb. But I had the truck with the oem bulb for only 1 month. I will give a try to seal with silicon when the temperature will be warmer.

There's a vent in the lights to prevent this. (Newer style)
It just came up and JJ had pictures showing the vent. It's mostly around the LED signal lights, They don't generate enough heat to burn it off.

It's from going from hot to cold. I have that problem with my switch backs, I do not have a vent. Just washed it and it stays outside.

There is also a TSB on the subject in the same thread.
