69 GT500 parking brake light.

Pulled the Shelby out of hibernation and the parking brake light is flashing. I never use the brake and it never flashed before. I checked to make sure the plastic tip was on the switch and checked to ensure it wasn't making contact and checked continuity. Also disconnected the wire to the switch and it still flashes. Anything common I should look for before I start digging deeper into it?
