Same thing happened to me. I just changed out my rear lighting. It is a bit complicated but if I have a problem with a taillight or turn signal that fails I have backup. I did have fabricate a bracket for the new license plate frame and there are issues with the way the stock taillight works that required running lines from the front signals to use on the rear turnsignal only lights. The brake light pulses if the turn signal is activated, but it stays constant when the brake is activated. I am not sure if the brake is activated when using regeneration braking (I have not had someone follow me to let me know if this happens still.
