replace rear cover and seal will sort it out, however try taking the cover off and pulling the seal out, clean it and refit the otherway round might solve it without buying one.

To sort the misting, get the backs off the light and in this weather it should allow the moisture to escape: if not get the old hairdryer in there

As Mac says, re seal and make sure the seal is good- either buy new ones OR swap left with right and right with left to get a better face. I also used a film of grease to properly seal- that stops it happening again

GummiPflege works well to help rejuvenate the seal.
I also turned the seal inside out and placed a piece of thick string underneath the seal to help pack it out a bit.

Out of interest, I'd also like to know where the drain holes are and whether they can be "poked" clean without removing the bumper etc.

The drains are from memory at the back? Two of them with 90° rubber tubes on

I’ll try to find a pic
