Parking brake light

I have a small round light sticking out of my dash in the same spot that the tach for a 65 formula s mounts. I found a light bulb and socket and wiring under the fuse box still connected to the parking brake lever. Does this light go into the small round thing in the dash. There is nothing plugged into the round dash thing it is just a threaded 3/4" tube with a clear lens and chrome bezel. I will be putting a manual choke cable into that hole and won't be using the light, I just wondered if anyone else has this set up.
P.S. I tried pulling the brake lever to get the light to work, but no dice.
