    As the title says my inboard brake lights do not light and no warning shows. Both bulbs check out good. LED tail lights are all working as are both back up lights.

    You are talking about the tail gate lights correct? Those lights are adaptive brake lights and are only turn on when you are braking at a high rate to warn people behind your stopping quickly. If you don't have any warnings then they should be working properly.

    This is my first bmw, so I'm still learning the ins and outs of the breed. Thanks so much for your excellent reply. I had one of the tailgate led tail lights out and replaced the circuit board with the LDD-500HW board from LED Supply with success.
