Under the dash, between the seat and the brake pedal is a switch. When the brake is released, it presses against the switch to turn off the brake lights. When the switch does not line up with or fails to connect with the pedal, the lights stay on until your battery dies, and it will.

Reach under the dash, check the switch and move it if it does not line up with the pedal. If it does line up but does not touch the pedal, twist the end of it until it does. The lights should go off.

check the sensors and connections may have loosened or knocked one loose if they look ok than have truck scanned most auto stores such as auto zone/advanced auto scan for free the trouble code will narrow the problem

if you have no ignition lights on your dash, no reverse lights and if when you start the car up the battery light stays on your ignition fuse has blown controlling these items. change the fuse. not sure if it is your ignition lights by your posting. if it is not please give a more detailed report,try to help if i can. hope this helps.
