I have no driver’s side low beam, but brights on both sides. This is a restoration car and here’s what I’ve done so far relating to the lights:
-Got a replacement driver's side short harness for the lights/horns…plugs into the fender well. I thought the problem was with my old one as it had a sharp kink in it and the wires seemed damaged. The low beam problem was there before replacing the harness.
-Replaced the Hella bulb in the driver’s side with an exact duplicate as OEM.
-Checked all grounds, but the power is getting there.

My turn signal/dimmer switch on the yoke has no tactile click-stops anymore (planned to replace it anyway). Plus, my turn signals aren’t working although when you switch one on, the respective corner lights come on continuously. Could this switch be the root of all the lighting problems?

Thanks in advance…
