First shut the vehicle off, then set the parking brake, then start it back up, the lights should remain off. Once you release the e-brake the lights will come back on.
yes, it lights up only when brake is applied

On the back of a car there are tail lights, turn signals, and brake lights. Cars also have back up lights that tell people when the car is in reverse.
Then the brake lights are out but the middle one still lights up. (:
Check for a short in your wiring harness or connectors under the dash. Particularly in the vicinity of your brake pedal. It could be rubbing on some wires.
with the park lights on both left and right side are lite. but when the brake is applied the right brake lights up and the left goes out(doesn't light up)
Try these: 19 BACK-UP LIGHTS 7.5 10-3 Back-up lights. 32 LICENSE LIGHTS 7.5 100-1 Parking lights, License plate lights, Tail lights.
you may have your brake light socket and your back up light socket in the wrong holes. Or you have a short but that would probably leave you with a blown fuse and no lights.
check for a loose ground wire

Under the brake pedal is a brake light switch that when you press the pedal it hits it and makes your lights come on..sometimes when they get weak the pedal depresses them simply from the weight of the pedal and they stay on..Have a friend get inside the truck and pull UP on the brake pedal as you look at the lights..if the brake lights go off when they pull up on it..then it is that switch under the brake pedal
