Power to all the dimmable lights in the car (instrument panel, performance gauge, radio, shifter, clock & heater switch) all come through the “INSTR” fuse and should have the same brightness for any position of the headlight switch knob. If all of these lights are too dim with the headlight knob turned full left, the problem could be corroded surfaces in the fuse block. Hard to clean but is a possibility. These little instrument panel bulbs don’t put out that much light at best. There must also be switching/contact surfaces within the headlight switch—beside the resistance wire and slider. Those contacts could be bad and no way to get to them. I think the heater switches are fairly generic for ’63-’64, anyway. New replacements for earlier years may or may not be available.

Would also like to know, my interior lights are too dim.
Hi group, I need help finding a headlight rheostat, my mechanic cleaned my current one but the results are dim interior lights at night, so I'm going to replace it.
Thanks in advance
Harry
