In order to meet the requirement that the vehicle runs in a dim environment, the headlamp in the advancing direction of the train is allowed to work after the power supply is switched on under the normal condition. The headlamps are generally divided into three operating modes, i.e., bright, dark and off, and the driver can select any one of the operating modes through a three-gear knob on the console.
