A little condensation that burns off with the head lights on could be considered normal, but if it stays then the assembly has a leak allowing to much moisture in the assembly, allthough I have not seen this on either one of my x-fires as of yet (condesation) I did have my h/lamp assemblies replaced on my 05 due the delaminating issues which a lot of us have had or still do, they were done at the dealer under warranty, but they did not have any problems with fittment. If you buy them new they could be expensive, you could look on ebay I have seen several assemblies for sale there. Not sure though if the euro models are different than the US models.
