Can someone help me with a step-by-step to diagnosing my flashing brake warning light (1973 1/2 911T)?

Here's the current state and what I've done so far:

- The brake warning light on the oil temp/pressure gauge is flashing. After a period period it was intermittent, it now flashes all the time

- I checked the brake warning switch on the master cylinder, cleaned at the connections as reset

- I checked my brake lights (my wife is not a very willing helper -- she hates my car -- so I had to wait to she was in an exceptionally good mood to ask for help) and they are not working. I checked the bulbs and they are good.

Could it be that the flashing warning light is due to the brake pedal switch having failed? I have not found anything in any of my manuals (owners, Haynes, etc.) that indicates that the warning light flashes when a bulb is out or the pedal switch has failed. Also, I have found no evidence that there is a stop light relay -- is this correct?

Thanks in advance for any help.
