Last week after cleaning my car, I noticed quite a lot of water in my rear light on my 01' 520i. I also saw a couple of dead flies in it. Arnt these lights supposed to be water and air tight. I took of the light and found no space of entry other than when I unscrewed the bulb. The bulb fitting seemed to be quite intact though. Any hints???
