Brake light sensors

Does anyone know what sensors the brake light relies on? It wasn't on until I swapped in my 8.8 and since then I have not been able to get it to turn off. I Ihave working rear brakes with no problems and a working parking brake. The pedal for the parking brake comes up all the way and there are no problems with the front. I know once before I had a rear brake line break on my D35, but once I fixed it and pushed the pedal all the way to the floor if cut off. What am I missing here? That light on light something is wrong is irritating.

I hope I reading your question right; but the brake lights are activated by a switch that rests on the brake pedal arm. When you release the pedal, it pushes in the switch and shuts off the lights. When you push down on the pedal it activates the switch.

Sometimes the switch goes bad, sometimes they switch falls off, sometimes the connector falls off, things like that. So look under the dash and find that switch that is activated when you move the pedal and you could possibly find your problem.

Oh, I think I got it, took a bit though for me to catch on. You mean the brake indicator lamp right?

The older jeeps it was just a switch on the emergency brake; on newer jeeps with anti-lock brakes its also tied into that system as well.
