Nope, all incandescent. I rang out each one, too. No opens.
Dusted off all the lamps.
Since I had the instrument panel off, I pulled the headlight switch and checked the rheostat action. It looked like the rotor terminal was not making contact with the whole rheostat coil thru the full sweep. On low settings, they are all dim, then the light flickers out. At 50 - 85% the dash lights are blacked out. Then at higher settings they all come back on.
I think the switch is defective. It won't make contact in the mid range.
