It could be a potential safety issue. Brake lights should work under any condition as long as there is enough electricity to power them. What if there's some communication fault with the FRM and CAS and the FRM doesn't know the car is on? Or some malfunction causes the car to turn off while driving?

Once you insert key, they should work. I think we were saying they won't work with key out.
