指示灯点滅装置。 A plurality of turn signal lamp groups each equipped on a trailer and a tractor, a pair of left and right turn signal relays that blink the turn signal lamp groups by operating a turn signal switch, and intermittently energize the turn signal relays. The turn signal lamp includes a flasher unit and a disconnection detection circuit attached to each of the turn signal lamp groups, which detects disconnection of the turn signal lamp and sends a signal to the flasher unit to increase the number of flashes of the turn signal lamp. Features a turn signal flashing device for tractors with trailers.
