I have regular lights. Did a search and didn't come up with anything. Last edited by roadrunner7070; 06/15/11 10:24 PM.

That's a sep circuit. (1) check the brake light fuse (2) see if the pink "in" wire at the brake pedal sw is hot (should b all the time) (3) engage the hazards & see if they flash. If all good so far seperate the dangling connector under the st col & the white wire is the hot "in" from the brake light & need continuity to the 2 "out wires to each brake light w the stalk in neutral (not sure on the colors) but www.mymopar.com has em live every 24 hour block of time like it's your last day on earth

I just checked and the dome/brake fuse is ok. The hazards are also working. I'll check the other stuff in the morning. Last edited by roadrunner7070; 06/15/11 10:48 PM.
