Inside of headlight lens fogging up

[alanforn]

I noticed after riding home in the rain today that my headlight lens had fogged up on the inside with condensate after I got home. I checked a few hours later and its still "fogged". I'm guessing it will dry out as this muggy weather is clearing out tomorrow. I did the HID conversion a few months ago, I thought I had taken great care in making sure grommet was weathertight,(used silicone also). I ride everyday but this is the first time I've noticed.

Has anyone else experienced this, should I be concerned?

I have done the HID conversion but used a gromit as I found silicone wouldn't stay in place. I once rode a 1000 plus miles in torential rain over a few day period but didn't have a problem as you describe. I would re-check that you have re-assembled the back of the headlight correctly as I think there is a rubber gasket which may not be seating properly.
