Driver's side brake light out
Tail light working, brake light isn't. Dual filament 3057 bulb was fine. Have voltage to the plug connector. Don't see any breaks in the lousy simulated plastic circuit board. Turned bulb socket to the lock position and nothing, although the side marker which is down stream is working. Process of elimination says it's the bulb socket. I have continuity from contact pins on socket ring to bulb contacts. 40 years of electrical experience and I'm stumped. Passenger side all bulbs are fine and light.
