what causes backup lights to stay on my98 jeep

Tail lights are a very important rubber feature on every machine. They are necessary when driving at dark, twilight hours, or in bad weather like rain and snow.

The purpose of your tail lights are to illuminate the rear of your car. Generally, they turn on when you flip the switch that also turns on your headlights. Many newer models accept them on an automatic sensor which turns them on when it detects a drib in ambient brightness.
Just similar every other role on a auto, tail lights can stop working, causing a major safety business concern. Not but is this unsafe for other drivers on the route who may not see your vehicle due to no lights in the rear, but yous can also get a ticket from the law, or neglect your state'southward inspection procedure for registration.
But what happens when your restriction lights piece of work and at the same time, your tail lamps don't?

half dozen Common Causes for Tail Lights Not Working But Restriction Lights Are
#1 – Bad Tail Light Fuse
The kickoff thing to bank check when facing an inoperational electrical component, particularly when information technology comes to bad tail lights, is the fuse.
A fuse is basically a metallic band inside a plastic container designed to pause when the electric current flowing through information technology becomes also high. This protects other parts of the electrical organization from becoming damaged.
There are generally 2 areas that comprise fuses in a machine.
- 1 is a fuse panel inside the cabin of the vehicle. This is normally in the front end passenger side, behind a plastic panel underneath the dash. In sure cars it tin can be found on the side of the dash with the passenger side door opened all the fashion.
- The 2d mutual area to find fuses is in the main fuse box nether the hood. It's a big black box that has a lot of wires attached to it. Once y'all have the cover off the top of it, yous can access the fuses within.
Each fuse controls a dissimilar electrical component, and their jobs should be listed on the covering you removed to access the fuses. If not, they can be identified by using the owner's manual, or by looking upward a year, make, model specific diagram online.
Once the fuse that controls your tail lights is identified, it can be tested using a fuse tester, which will light upward if the fuse is good. If it doesn't lite up, the fuse should be replaced with one of the same size and amperage. On certain fuses, you tin visually see a suspension in the metal wire inside a bad fuse.

#2 – Bad Tail Light Bulbs
If the fuses under the hood and inside the cab bank check out fine, the next culprit to look at are the tail lamp bulbs themselves. This generally involves removing the tail light cover, although some cars have an access panel where you tin accomplish in and twist the bulb out of the lens.
The best way to place a bad bulb is to remove it from the socket it is plugged into, and closely inspect the filament. The filament is the wire inside the bulb that creates the illumination. A broken filament means no illumination and y'all volition need to replace it with a new bulb.

#3 – Socket Failure
Sometimes the socket the bulb gets plugged into can become bad. Usually this is caused by corrosion, which is caused my moisture inbound the socket. However, information technology can also end up declining due to poor connexion of the wires in the back.
If the bulb and fuse both check out good, cheque the status of the socket while you lot have the bulb out of it. Wait for any discoloration, similar white, blueish or brown, and bent or broken pins.
Information technology is also a practiced idea at this point to check electrical current with a multimeter at the socket. No electricity reaching the pins means a failure somewhere up the electrical line.
#iv – Worn Out Wiring
If there is no electrical current reaching the socket, and fuses have checked out proficient, it is very probable in that location is a damaged or broken wire somewhere along the line.
At this betoken, you'll need to obtain a wiring diagram and visually inspect the wires along the tail lite excursion for broken wires or cracked insulation.
Be certain to check the body grounds coming off this circuit likewise. A muddied, loose, or broken basis wire will cause a failure in delivery of electricity to the sockets as well.

#five – Control Switch Failure
Another crusade for tail lights not turning on is the switch that controls them. The head low-cal switch on the dash tin fail equally well, and should be checked of everything else has checked out good.
Normally, this switch turns on caput lights, tail lights, and parking lights. If all other parts of the tail light circuit are in proper working order, it's possible this switch has failed. This can be pulled out from the nuance and checked with a multimeter to verify it has failed.
#six – Dirty or Bad Ambient Light Sensor
Many modern cars also have an ambient light sensor on the dash. This allows the vehicle's computer to automatically plough the head lights and tail lights on and off according to how lite or dark it is outside.
Some also turn off daytime running lights on newer vehicles. If both your parking lights and headlights don't plow on just your restriction lights still exercise, this is the likely culprit.
If this sensor goes bad, or gets too dirty, it cannot tell if information technology is calorie-free or dark exterior, and may not turn on the lights. But again, this would affect both the head lights and tail lights, and could exist easily tested by manually turning the head calorie-free switch to the on position.

Conclusion
Overall, tracking downwards an electrical failure can exist tricky and frustrating. Thankfully, tail light bulbs normally run on their ain isolated excursion, then problems tin be tracked down with relative ease.
All of these failures will cause the tail lights to non work, but volition all the same allow brake lights to turn on when the pedal is depressed as the brake lights run on a different line of circuitry.
Once a driver realizes their tail lights are not working, they should immediately address the problem for their own safety and that of others.
