The first domestic (U.S.) built car I have seen with "back-up lights" was a 1958 Chevrolet Impala. The center light was white of the three "bullet" tailights. Other cars may have had them as "add ons" purchased at auto accessory stores
how to trouble shoot for gmc back up lights?
"Back up lights" are the same as reverse lights. Lights that "turn on" when vehicle is put into reverse gear to illuminate the rear of the car so you can see when backing up.
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.
The first thing I'd do is check the fuse. If the fuse is good the you might have a short in a wire somewhere.
the #3 slot is for the parking lights #11 is for the warning lights #21 is for hazzard lights and #26 is the back up lights the #3 slot is for the parking lights #11 is for the warning lights #21 is for hazzard lights and #26 is the back up lights
yes, it lights up only when brake is applied
It turns the back up LIGHTS on, on the rear of the truck.
The back up light switch is stuck closed or broken.
On an average car, there are high and low beam lights for night driving, clearance lights on the front and back, front and rear turn signals, and back-up lights used when backing 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.
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.
Check the fuses first. If the fuses are ok check the reverse switch. The switch is under the dash on some models, and on the transmission on others. A bad or misaligned switch is the most likely cause for no back up lights.
