I've just fitted a pair of used black headlights to replace the chrome ones.
Since fitting the black ones seem to mist up on the inside where the chrome ones didn't?
I swapped the backs off the old ones and cleaned the seals, also swapped the rubber drain tubes but it hasn't helped

has anyone else had this problem?

They all do it from time to time, but they clear themselves. Mine does it when theres a drop in outside temp.

That will also let the moisture in. As Phil has said they do mist up from time to time along with the rear lights on my

Before you do that, a simple fix is to wipe some kind of common household chemical on it (not vodka)

Will find out soon enough and let you know. Its on a bike forum I frequent and I cant find the thread.

A wipe on the inside with meths or a wee bag of silica gel left overnight should help so Ive found out.......

Better than getting the deWalt out?

Thanks for the tips Davie - the headlight doesn't come apart so i can't get to the inside of the glass - not sure about pouring the meths in?

No. The light already have breathers to let moisture escape. If theh did not they would explode with the heat build up in the units.
We will all have condensation from time to time and nothing to worry about unless you think it is excessive and may have a leak that is letting water into the unit.
Nothing other than the heat in lights and cold nights to blame. Just same as the condensation inside your car.
