Try disconnecting the brake switch by pedal and see if they shut off, if they do, it's the switch if they're still on, you have a short and will need to start tracing curcuit disconnecting harness plugs starting from rear lights

I believe that the BCM controls the brake light on your truck. The switch signals the controller that the brake pedal is depressed. You need to look at data stream for BCM and see what the BCM is seeing in relation to the pedal sensor

Under the bed where the wires attach, they can get worn and crack after awhile. Since brake lights work on a ground circuit, could be a bear wire touching ground.
