I just got in from poking around under the dash again and found what I believe is the switch. It's at the very top of the pedal assembly and quite inaccesible. Thinking I'd have to at least partially remove the pedal assembly to gain access, I looked in the Haynes manual again and found a diagram of the assembly complete with switch. It shows up in the wiring diagram as well.
Looking at the wiring diagram, it appears that the low brake fluid switches also actuate this light. Tomorrow, I might see if I can somehow close one of the low-fluid switches to confirm that every thing else is OK with the circuit before I tear into the pedal.
I'll keep you posted.

As far as I know the brake light comes on when your front pads wear thin and maybe if low on fluid. P.S. My 1980 240 has been parked since November, I am getting ready to put a battery in it and get it going so I can make sure its ready for a run to California in April.Max

I replaced the bulb with a known good one but it still doesn't work. I did have the key in the 'on' position. Next step is the brake switch. I looked under the dash near the pedal and didn't see anything that looked like proper switch. There's no mention of it in my Hanyes manual and I couldn't find anything on this group and through internet searches. The light DOES turn on when the p-brake is applied with this car, right?
