Condensation in headlights

Hello,
Sometimes I see a part of my bi-xenon headlights inside covered with condensation.
(both lefthand and righthand). Is this normal?
Our BMW x3 is from november 2012.
Have anyone the same experience?

Regards, Sjoerd

There is a SIB for this from back in 2011:

Summary: Bmw: heavy condensation on xenon headlights. In heavy rain conditions or high humidty, condensation may build up inside one or both headlight(s). The condensation is still present even after a few dry days. *js

I had water in the lights and took the car to the dealer who disassembled the light and dried the moisture with compressed air. This really helped, although they still fog when I start the car on a cold morning. May ask for a new gasket if it gets worse.
