Abstract

PURPOSE:To reduce wiring in a device for decreasing possibilities of erroneous wiring by containing a terminal to connect an automatic flasher, a contact of an output relay, a changing switch, and a load control relay in a casing. CONSTITUTION:An on/off time of an output relay is set in a CPU, and a changing switch 6 is changed into an auto mode. As the surroundings are dark, a contact 2a of an automatic flasher 2 gets on. When a contact 5 of the output relay is on, a load control relay 7 gets on. When a contact 5 of the output relay gets off by a timer 4, the load control relay 7 gets off. The changing switch 6 is changeable among the auto mode for putting the automatic flasher 2 on/off by the timer 4, a test mode for putting the load control relay 7 on forcedly, and a disconnection mode for keeping the load control relay 7 without actuating. By containing these in a casing, wiring is reduced, thereby possibilities of erroneous wiring can be reduced.
