turn signal flashing weird

[Schnitzer318is]

probly a corroded plug or a short in the wiring somewhere. The front signal harness is a known wiring issue in e30s

What he said, had the exact same problem with an '87 325 I bought for the wife. Check the plugs that actually go into the lights for corrosion, that's where my fault was.

ok so I replaced all the light bulbs anywhere on the outside of the car now, and everything works now except for the drivers side front turn signal. now, it does light up, and it does flash, but its dim as hell and the whole left side flashes rapidly as if a bulb is burnt out. the rear left one is as bright as it should be but like I said, just the front one is dim on that side. is there anything that could be causing that? and to be honest i didnt even know I had light up sidemarkers til today when I was checking the wiring, and I replaced those bulbs too and they work also now. woo!
