The lighting system(see as figure 3) is controlled by the external lamp switch 52307, the switch power comes from two sources, the current of the width lamp, tail lamp and license lamp is connected with No.30 wire (battery positive pole), as long as the switch is at the 1 or 2 gear, it is passable, and the current of the head light relay coil is led to cylinder 4 of switch 52307 from the igniting switch, if the igniting switch is cut off, the current can not be connected with the headlight. If the external is at 2 gear, one of the relay 25009 of high beam and the relay 25008 is closed.
