It is not the fuse, bulbs, or neutral safety switch. What can it be?
It is on the same circuit as the brake lights, but if they are not working, and the bulbs are good your switch needs cleaning or adjustment.
Attempt this first since the switch costs nearly $300 bucks.
On the passengers side of the trans just behind the bell housing there is a fan shaped switch, loosen the 12mm bolt ( smaller of the two, and rotate the switch while a friend checks the lights. this problem is usually accompanied by an occasional inability to start the vehicle, but can be cured by jiggling the shifter.
While adjusting the switch make sure that the vehicle will start in park as well, remember to block the wheels while testing the back up lights, engine off, key in run but not start, shifter in reverse, move switch until lights come on.
Once you find this spot, hold it in place and have your helper check to make sure it will start. This may take several tries to get both working correctly.
If you have no luck the switch may be dirty, this happens a lot. Hold the post to the bottom large bolt still while you loosen the nut, then remove it, then remove the 12mm adjusting bolt on top, remove the wire connector and pull the switch away, remove the bolts on the switch and separate the halves, use electrical contact cleaner and maybe some q-tips to clean all the copper connections completely apply di-electric grease and reassemble, refit to the trans and readjust so all functions work, this switch controls back up and start safety.
Caution! always hold that bottom bolt while tightening the large nut, this is connected to the gear adjuster and you could damage the internals if it isn't secured while you do it.
Check the fuse, and the bulbs, then the switch on the top of the brake pedal
No.No.
brake relay or sensor
It only allows starting in park and neutral, and runs the reverse lights.
Short circuit in your vehicle alarm system. In most alarms, some lights will flash on and off as an indicator of an attempted break in.
Yes. There is a switch on the tranny. First, check switch wiring. Make sure it didn't become unplugged or damaged. You don't need a part #. Just call a parts store and ask for a new switch.
the reverse switch in the transmission
No.No.
try unscrewing the back light covers and replacing the lights
YES. The harness is behind the bumper in proximity of the location of the lights.

my fuse panel (with the descriptions) is gone off of my 2000 jeep grand Cherokee Laredo, how to i get a description of what all 32 fuses control on my jeep?
Try replacing the turn signal flasher
Turn on you lights and put them on low beam. That is daytime running lights.
brake relay or sensor
It depends on which lights are on. There could be an issue with the oil or the tire pressure or you may just need gas.
They aren't. The brake light circuit is not connected with the headlight circuit.
You may have to pull the fuse. I t has happen a few times on my 95 Laredo. Look in your manual for the fuse that control the lights.
