Mine too, only noticed it yesterday and put it down to the amount of rain we have had lately. Will keep an eye on it and hope it will go when the weather improves. It is going in for its first service on Monday so if it has not gone by then will ask the engineer his opinion.

Someone said they would not put silicon on the lights i really don't understand that after sealing mine around the top edge i have had no further steaming up at all.

The lamp assembly is located by two spigots on the forward edge and the two screws on the inner edge. There is no seal between the body and the lamp assembly, so a strip of silicone on the upper edge is unlikely to address the issue. The weather seals are at each individual lamp fitting. If damp is getting inside, then either one of the lamp fitting weather seals is not seated or there could be a crack in the casing. 10MY (Sept 09) TD4 HSE Auto in Stornoway Grey (Now Gone)

What condensation mine's fine thankyou

Dealer told me LR will only consider it a problem if it doesn't clear or starts streaming down the light!

To re-raise this subject, I'm having trouble with one of my rear light clusters that is leaking between the unit itself and the poly lens. I have tried sealing it twice with silicone sealant but it appears to work only for a while at best.
Can anyone recommend an alternative sealant I could try for a 3rd attempt?
