Bike - zx6r B1H. Stupid problem really but it's still a problem. It's been like that for a while (a little bit on dipped light and a lot on high beam as it's not used a lot) so I decided to get it sorted. I dried it all out usig a hair dryer, also I put some red rubber grease on cover seal so no air gets in there. Took it for a 30 min spin to the cafe, stayed there for 2h and when got back, it was same again - dipped was misted up and high beam has drops of water runing down a inside of a headlight. I'm puzzled so any ideas will be greatly apreciated!

don't know if it would be feasible to do inside a motorbike headlight but in my old skyline always had the same problem so i used the little bag of silica gel from a shoe it did the trick.

haha. I had a skyline too! Rear light always got condensated. I took the whole cluster out, dried everything out with a heat gun and then sealed it up good and proper with Dum dum sealant.

The thing about a hair dryer is it won't be guaranteed to effectively dry in a confined space, what you wind up with is hot humid air inside the cluster which can return to moisture and liquid when it gets colder.

Desiccant packs are the way to go to dry it out at the start.

It was the front headlight with me :)

Wish i had never sold it the dam thing :(

lights have to 'breathe' if they don't then they will mist up. condensation will only burn off if given enough time to do so so short trips will just make matters worse.

sealing them up is bad as there is nowhere for the heat to escape.
