Just found a photo on eBay of the back of one of the lights and also an exploded diagram of the same cluster in the parts catalog, so the white panel comes off and there is a pair of incandescent bulbs in there and a seal to keep it dry. Time to take this apart and dry it out and make sure the seal is sealing properly. Maybe it wasn't installed correctly at the dealers.

It will be interesting to see what you will find there Lee.
Also, don't forget that most of the ''single glazed'' things will condensate to some point.
I bought brand new OEM FL tail lights and they so condensate a tiny bit depends on outside temp and water temp, I think, but not badly. If there is any water inside that wont obviously help with unusual amount of condensation.

If you can take the light off and keep them at home overnight in warm condition and put some Silica gel packs inside then I'm sure you'll be able to get rid off all the moisture from inside and then all whats left is to find where the water comes from and make a new good seal

I've stuffed some small sachets of silica gel behind the trim in the boot. I'll report back on how it affects the rear lamps soon.

Almost no effect, unfortunately. Any other ideas, other than removing the cluster and waving a hairdryer at it?

On that light there is a small plastic cap, is there room to run a hose to a small container full of silca gel so the light has a expansion vessel but a dry atmosphere?

Ironically, I was just about to do mine this weekend, but whilst out yesterday, noticed that it had all gone and was bone dry... must have something to do with the overall ambient temperature. I noticed that it has still been in double figures even at night for the last week or three.

I put big packs of silica gel behind the covers on all my lights front and rear.
Also cleaned the seals with a cotton bud and silicone spray.
I seem to recall this was not possible on the facelift rear lights but I fitted them in the dark in a rush so can't remember but they were more like sealed units IIRC. It seems to work but in very code weather I can get the odd bit but not like before.
