It's gotta be the battery/electrical. Prob a corrosion in the battery line that shocked the electrical system get it towed to a dealer and tell them your story.
It means that one or more of the gauges is out of the safe zone.
Have vehicle scanned to determine the problem
Yes, it means that there is an electrical problem with the back up sensors in the rear bumper. You will probably have to take it to the dealer for repair.
If the ABS light is on the ABS system has a problem and is not functioning. Until the problem is repaired the light will remain on. Take it to a mechanic and have it diagnosed.

Your 1992 Jeep Wrangler faulty gas level sensor will cause the gas gauge to not function properly. The gas level sending unit may have a bad ground wire.
If it is the light in the gauge console, it is to let you know the headlights are on automatically. Like when the windshield wipers are on, or that its dark enough to have them turn on.
If the check engine line is flashing then that means there is a real problem and you should have it looked at, But if the light is on and NOT flashing the it is most likely a problem with the emmisions system and most likely an oxygen sensor.
