Like German vehicles like an audi q7? Or are they in line with brake lights and are dim at night and come on with your brake light? Or are they bright and stay on full time like a an audi's?

MOPAR Accessory Kit rear foglight:
They are bright compared to the rear tailights so yes they function like the Q7.
The kit is wired into the foglight trigger circuit for the front fog lights, If you don't want to mess with tapping the wire from the fuse box like the installation instruction suggest you could always find another source for the run/start signal and add a switch inside the cabin to trigger the rear foglights so they would be selectable. (This only uses a single filament bulb)
Taillight solutions RFUK (rear foglight upgrade kit)
This is a misnomer because they are really additional tail and brake lights. The foglight housings are used and the sockets are changed to a dual contact instead of single contact to allow them to mimic the Brake/taillight function.
I personally prefer the RFUK because they give added visibility to the rear of the vehicle in all conditons other than fog.
The RFUK could also be modified to give you a selectable "true rear foglight" function by adding a relay harness and some diodes so when you active the rear fog circuit it would override the brake/tail/turn fuction.
If fog conditions were good enough to drive in I would probably use my 4 way flashers when I was on a two lane back roads if I think other driver may still have trouble just seeing my taillights.
