It could be a ground problems .. if ground at brake lights is not good then it could take it through back up lights
check all ground to rear end like parking lights,brake lights, back up lights and flasher
if you have a trailer harness check connections for trailer could be a big problem
hope it helps

SOURCE: Brake lights

If you have an aftermarket trailer towing plug on it, that's where i would look first. Something is shorting out in there, or you have a broken wire or ground somewhere. Proabably near the back where gravel stones can hit.

Why does brake assembly fail when I press pedal?

Check for loose contacts or wiring that is causing a short circuit near the brake pedal, or at the rear light.

Need to find the reverse wire to hook up a peak backup camera thanks ernest

You did not specify the yr and model of your vehicle, but the procedure is the same, remove the tail light assembly as specified on your owners manual to replace a light bulb. Apply the Parking Brake and turn the ignition switch to the RUN position (do not start the vehicle), press the brake pedal and place the Shifter in REVERSE. Remove the Reverse light bulb and use a test light grounded to the vehicle chassis to find which one of the two wires going into the reverse light socket is the 12v+, once located, replace REVERSE light bulb, place shifter lever in PARK and turn key OFF.
Splice the 12v+ wire and connect the 12v+ lead from your camera to it, get your Ground (-) from the vehicle chassis.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

Problem with brake lights and can't shift out of park without pressing the shilft lock override button

Most likely the brake light switch has failed. This is on the brake pedal under the dash, if you can move the seat all the way back, you can lay on the floor, look up at the pedal and you should see a small switch with two wires on it, attached between the pedal and the rod that goes into the master cylinder. usually there is a spring clip holding it on, pull this, separate the rod, the switch, and the pedal. carefully unplug the wire harness, then reverse the process to install the new switch.

'00 TJ brake and 4way lights not working

Check the brake switch on the brake pedal for your brake light prob. There are 2 wires on the switch, one is 12 volts and the other gets 12 volts when you step on the brake pedal. You can check tis with a test light.

No brake lights

First Start with the Stop lights fuse Check and make sure it's good if questionable just replace it. Check to make sure you have power going into the fuse Use a 12V test light or volt meter. If you have power going into the fuse make sure the other side of the fuse has power through the fuse. Next Go to the brake light switch and test for power going into the switch if you have power put your tester on the other wire on the brake light switch and press the brake pedal, If there is power the switch is good and if not the switch is either out of adjustment or bad.
If you have power in and out of the brake light switch with the brake pedal pressed then you have to find the breadk in the wire back to the lights Oh don't forget the bulbs and the grounds for the bulbs.
