1990 BMW 735I User Comment / Complaint

This mustard colored module causes the computer to warn the driver of a failed parking light and/or tail light when the headlights are turned on. every time these lights are turned on, this module sends a signal to the driver. upon inspecting the lights when this warning occurs, the lights are fully functional. however, about one third of the time these lights (the front left parking light, the rear left parking light, and the right rear marker light in the bumper) actaully fail. these lights fail even though their fillaments are still good. what is causing this problem is a cracked solder joint inside of this mustard colored relay.
