On the transmission lever there is a backup light switch which makes contact with the backup light circuit when you place the lever in R. The circuit then sends current to the backup lights and they come on. When you move the shift lever out of Reverse, the circuit is broken and the lights go out. The problem you probably have is a dirty swicth where the contacts meet from the lever to the switch. If the contacts are dirty, you will get intermittent current to the lights. So find the switch on the lever, use some rubbing alcohol to clean the contacts and it may fix it. If not, then your backup light switch may be going bad, but try cleaning the one you have before investing in a new one.
Check the circuitry to the backup lights. The same fused circuit is probably used for both brake lights and backup lights. As you go past Reverse, the backup light probably is turned on briefly, causing the fuse to blow. It's just a thought, but I'd think it worth checking.
It is not really a circuit, traffic lights in todays world are controlled by programable logic controllers or a plc. There are rungs of logic to control the changing of the lights which are known as the inputs and outputs where the voltage is controlled to change the lights from red to yellow and green.
If the lights are the load of the circuit, then the lights will be off if the circuit is open.
how do you replace backup lights on 99 grand am?
No they aren't on the same circuit. The fuses are in the glove compartment under a panel on the left side...beside the trunk release if you have that option. When you hit the horn are the backup lights going on? or the lights turning the horn on? If so you have a bad ground wire.
sirs if you could explain me detail about the staircase lighting ckt diagram & explain how does the switch function.
It doesn't have any. The only C2 (1963-1967) with backup lights is the '67.
Go to a parts house that carries a Haynes Manual. They have them for specific cars.
There is no relay for the backup lights. The circuit is powered by the keyswitch, runs thru a 10 amp fuse on the interior fuse block, then goes through a switch mounted on the transmission, and on to the lights. The switch is on the front of the manual transmission, and on the lower front of the automatic.
Just an added update.., all fuses seem to be good with clean connectors. Also the signal lights quit too..
Which fuse works the backup lights, heater fan, and gas hand will depend on the make and model of the car. Each car manufacturer configures their fuses in different ways. One can consult the owners' manual of the car to find a fuse diagram.
Lights are off when the circuit is open.
The switches to activate the backup alarm are usually placed within the transmission. If you don't feel like going through this hassle, you can connect the positive wire for the backup alarm to the circuit which activates the backup lights, or you can put a manual switch in the cab to work the backup alarm.
Lights are on in closed circuit. It means that is a current flowing when circuit is being closed.
Tail lights. Brake lights. Backup lights. Signal lights. License plate lights.
The circuit breakers in a panelboard feed separate circuits. The lights that stay on are on a different circuit than the ones that go off. To fine the circuit that feeds the lights that stay on, go to the panelboard and turn off the breakers one by one until the lights go out. This is the circuit that feeds that circuit of lights. Remember that lights and receptacles can be on the same circuit together.
There are two backup lights next to the red tail lights.

replae backup light switch on transmission
NO - They all have there OWN circuit & are powered by a fuse or fuselink.
