Condensation in headlight

Is there not supposed to be some kind of cover on the back of the headlight housing? My Mazda6 was awful on burning up halogens and I was in there a lot (multiple times a year). Each section of those 4 lamp housings had access covers with gaskets to seal them. There was one on each end and one central one for the two lamps in the middle.

My BMW Z4 also has some condensation issues. It is from a weak foam seal on its housing covers. The only way to get a new seal is to buy the whole cover. I have put some sizable dessicant bags inside the housings and the problem has gone away. Not a true fix, but a solution.
