I am posting here in case anyone else has the problem. In my 1988 MKIII my tailights were doing very odd things (even pulsing in time to the sub woofers). I could never be sure they worked at all and had friends follow me to tell me what they were doing.

Well.. I pulled the rear lights off, replaced the seals (they were old and cracked.. good thing to do) and then looked at the wiring. Inside the cover that holds the lights, I found 2 screws that hold what looks to be grounds. Surprisingly they were backed off almost 2 full turns. Tightened them and the lights work perfectly.

This may be a normal issue over time or just someone being careless.. but its a quick thing to check if you are having that issue. I cant find my original post regarding this so I just posed the solution to my problem in case anyone else has issues and this helps.
