Headlight Condensation HR

[Olly350z]

Fitted my HR headlights today and I absolutely love them! Slight snag is that the passenger headlight is wanting to steam up slightly. My first port of call is going to be trying to pinch the spare rear seal I have and see if that cures it, if Not I'll buy new from Nissan. 

 

However, has anyone found a cleaver way of curing this? What have you used or done? Drilling holes is not an option before anyone asks haha. Where are the ventilation holes on a HR Headlight? I wonder if mine are blocked 

 

Thanks everyone
