On my 69 Z with console gauges, there are no lamps in the GEN,OIL PRESSURE locations, only turn indicators, bright lights, Brake and Low fuel and that will only come on when when the fuel is low enough to ground out the lamp to make it light. It does not come on with the ignition. Not sure about the brake light as when starting it is already on. But if I had to guess I would say no as it is also a ground connection.
