Abstract
Left and right lamps or rear are connected to a stop lamp switch or a turn signal switch by left and right relays. When the turn signal switch is made ON to left and an intermittent signal is inputted from a flasher unit, a left relay is made ON by an output of a left integrating circuit and a left lamp is flashed in accordance with the intermittent signal. During the time period, an NAND circuit for inputting the intermittent signal is made H. Since a right relay is made OFF, when the stop lamp switch is made ON, a right lamp is continuously lighted. Thereafter, when the turn signal switch is made OFF, the NAND circuit is made L and the left relay is made OFF by rapidly discharging the left integrating circuit. Thereby, also the left lamp is shifted to light continuously without delay.
