ABSTRACT:
If an ignition switch of a vehicle is ON and the vehicle speed is not zero (i.e., the vehicle is travelling), the lighting of a work lamp is prohibited even if the work lamp operating switch has been set to ON. This ensures that a work lamp does not remain lit by mistake while the vehicle is travelling, and that battery consumption by unnecessary lighting of a work lamp is minimized.
