Last summer I had rear bumper removed and reinstalled on my 87 S4 Auto to do some minor body work.
Recently, my stop and marker lights started to blow one after one in both tail lights. I mean literally blow in pieces, bulbs that is.
When changing bulbs, noticed that there is water in tail lights housings. Blew water out, changed bulbs, everything is OK, but after rain here it goes again and again. Cant see where and how water gets in.
Any thought on that?

Porsche had a "remedy" for this that includes drilling a ffew drain holes in the bottom of the taillight wells where the water gathers. I used a 3/16" drill but and put four holes in each well. Following that, I added some thin foam weatherstrip to the perimeter of the tail light housing so that less water would make it in there to start with. I was trying to remedy the flood of crud that seemed to wash out of there and drip down the bumper face after every wash. It would serve the same purpose for you, hopefiully in both directions.

Be sure the lamp sockets are sealing correctly on the housing too.

Remove your tail light housing and check thke grey area for cracks. Particularly in the crease between the upper (turn signal) and lower (tail light) reflectors.

21W bulbs get very hot, and if they are on for a longer time and get too close to the housing, it can crack and deform. Happened to me twice.
