It's a brake warning light. There's a valve that is centered in the pressure differential valve (the metal block down on the frame where all your brake lines converge) that will trip a switch if you lose pressure in either the front or the rear brakes. This valve also will go off-center when you bleed your brakes and can really be a PIA to recenter.
Check the bulb first to make sure it's in there and is good and then make sure the wiring is plugged into the pressure differential valve.

Mine is the floor illuminator light. It's still got the cover on there so it's red and the light points downward towards the floor, kind of like the neon lights on Civics or whatever. Its place on the dash is taken by my 'mystery switch.'
How hard is it to re-center the valve? Taking care of that is something that I'd like to do once I clean up a few other things.

Thanks,
The guy before me had lost part of it, so it dangled under the dash where it shorted out and burned up two wires, one of those wires ran to the instrument panel, then back down towards the wipermotor firewall area, I cut them out, but now have no dash lights. I may go ahead and splice it back in.
