When the stop lamp switch (3/9) is closed, a signal is transmitted to the central electronic module (CEM) (4/56). The high mounted stop lamp (10/19) is supplied with power directly from the central electronic module (CEM). The central electronic module (CEM) supplies power for as long as the stop lamp switch is closed.
