  • Publication number: 20230141000
    Abstract: A motorcycle includes a brake lamp, a brake operation unit, a first switching unit, a second switching unit, and a brake controller. The first switching unit is switched a circuit state so that a driving current is supplied to the brake lamp while the brake operation is being performed. The second switching unit is switched the circuit state between a closed state in which the driving current is supplied to the brake lamp regardless of the brake operation and an opened state in which the second switching unit is not electrically connected with the brake lamp. The brake controller controls to actuate the brake and switches the second switching unit from the opened state to the closed state when the brake activation condition is met.
