Why would your back up lights not work when you put it in reverse if its not the fuse or light bulbs?
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.

Why would your lower brake lights not work when the upper brake light does work?
By the nature of the question I assume that you are referring to the tail lights and brake lights. My Explorer has four bulbs. Tail, brake turn and backup. They are all in separate compartments of the light assembly. So it could be that you have just burned out one bulb. If you are referring to the upper brake light in the rear window or at the top of the tailgate, same thing. One or more bulbs are burned out. I see people driving all the time with both lower lights burned out and the top working or visa versa.
Why do brake lights stay on when car is turned off?
I hope this helps, I would take a calculated guess that it is strictly a safety factor (in an emergancy on the highway if your foot is on the brake you are less likely to be rear ended) and if this is indead true, than it is wired to the battery independent of your starter switch If the brake lights are staying on even with your foot off the brake, it may be that the switch controlling the brake lights is broken. Beware; this can drain the battery.
