STOP LAMP DEVICE

A stop lamp system includes a control apparatus that controls a turn-on state of a stop lamp based on a turned-on/off state of a stop lamp switch in conjunction with an operation of a brake pedal, a turned-on/off state of a stop lamp turn-on request signal and a turned-on/off state of a stop lamp turn-off request signal. When the stop lamp turn-on request signal is in the turned-on state and the stop lamp turn-off request signal is in the turned-on state, the control apparatus gives priority to the turned-on state of the stop lamp turn-on request signal and turns on the stop lamp.
