When i press my brakes in my 04 rubicon my right light will not turn on, but when parking lights are on the light will turn on but will not get bright when brake is pressed.
Not sure how this fixed the problem, can't remember the last time I had a third brake light and that certainly hasn't given me problems.I figured it out, previous owner removed third brake light and left the wires open and not completing the circuit. i just put a load between the + and - and it fixed the problem
They are LEDs which means they are no longer grounded through the mounts. Looks like bad wiring job or multi function switch.I'd say ground problem them cages tend to be a PITA . My first Tj had them they worked then didn't work . Take a wire hook it to your bumper and put the other end to your light .
