In this video I explain how I fixed my lighting issues with my E36. The issue ended up being a combination of the headlight switch, high beam fuse, and crunched trunk wiring. Here were the issues before fixing everything: the cluster backlighting and buzzer did not work. 3 of my tail lights/brake lights worked which was confusing because all of the bulbs worked fine. After a while one tail light stoped working completely and the other one was constantly on until I disconnected the battery. Hope this helps!
