Very common problem ,easiest cure is just drive about for a while with the rear cover off , then to place one of those silicone jel satchet you get free with electrical gear in the back of your head light to assorb the moisture

Thats funny mine fogged up today for the first time on the nearside. I thought it was down to me changing the side light bulbs the other day. Letting in the cold air.

probably was graham what i should of added was put your lights on when you take the cover off

When putting the nightbreakers in I lost the cap down in the engine block. Over the next week it fogged up with moisture. In the end I taped the paint up around the headlight - ran the engine and put all the lights on. Then used a 500w worklight right next to the lense cover to warm it up. Once it had all gone left the car in the garage all day to get the temp back level. This was after I replaced the cap.

If you are getting moisture in it suggests that a seal has gone somewhere allowing moisture in.
