Night time brake lights not working

For some reason my brake lights don't work. They work when I don't have headlights on, but when I turn my headlights on they don't come on as the running lights, but if I push the brake they work. I replaced the brake switch fuse and still nothing

Sounds like you have bad housings, very common on the WJ. You can get new ones on E-Bay for about $35 each.

If you don't have time to do it right the first time, how do you have time to do it over.

I recently put the CG LED Taillights on my WJ and found that the aftermarket connector for the taillight housing did not initially seat completely with the stock connector, then when I made it fit, it pushed a pin into the stock side connector. Pulled that out and carefully connected them and no issue now. Check the connector on both sides and look for bent/pushed in pins.

I'll check that but it was working when I plugged them back up

FWIW, mine worked fine for a day or two, then acted up when I pulled them back out to replace the cheap incandescent bulbs they shipped with better incandescent bulbs for the reverse and turn signal.

It could also be improper resistance with LED bulbs if the housings were set up for incandescent bulbs - if you have the old bulbs try putting them back in and see if that is it.

I did and unplugged to see if I had bad prongs and they are good

Just to let you know, that's only for turn signals. The resistance is for the correct capacitor discharge in the flasher module. That's why, when there's no resistor with the LED, or a bad bulb, it hyper-flashes.
