I have been Googling for a while looking for info on troubleshooting turn signal issues on a 2012 328i. I have found a ton of threads here and elsewhere on issues with the LEDs and the LCI modules, but since these are regular incandescent lamps, I am not able to find much info on issues like this.

Last week it started with the rapid flash on the left with the rear signal not flashing. Then the next day both the left and right rear were not flashing but the front and side are still working. Both rear lamps are good. Testing the socket assembly shows connectivity through the lamp in the socket.

Any help or pointers in the right direction would be greatly appreciated.
