Brake warning light??? Help.

Hey y'all I've got an issue i know someone on here knows how to fix. I have a brake warning light on the dash, that stays on whenever the key is on. Is it a pressure switch in the brake lines or something to do with the parking brake? I've bled my brakes like 5 times to try and get it to shut off, but it hasn't. Is it from the proportioning valve?
Thanks!!

Has nothing to do with the parking brake.

C8AZ-2B264-A .. Brake Warning Lamp Switch / Available from Ford & auto parts stores.

Applications: 1968/79 F100/350, Bronco & Econoline / 1968/69 FoMoCo Passenger Cars.
.
This switch threads into the Brake Pressure Differential Valve that some people call a proportioning valve.

This switch is plastic and a notorious POS! Cracks develop within its threads causing brake fluid to seep out.

When this occurs, the warning lamp on the dash comes on...and stays on!
