Water in tailight. How I removed and fixed it.

A common problem in the G8 rear tailights.

Nice video. Had the same problem, but the condensation was being caused by the sunroof drain tube pulling out of the grommet in the body and filling the well below the battery with water. Tried your methods here first and was still getting condensation inside and a leak in the back seats.

What i used to do to my old volvos that had crap gaskets is drill a tiny hole on the bottom of the housing
