Abstract
An electronic flasher system adapted to change an operating sound in dependence on situations surrounding a vehicle when the vehicle changes its direction or lane, so that the driver can grasp the situations surrounding the vehicle by merely listening to such operating sound. The flasher system includes a flasher circuit 21A connected with a sound generator 3 for generating operating sound, and a situation detecting sensor 6 for outputting an output signal in dependence on a running state of the vehicle. The flasher circuit 21A causes a change of the turn-signal operating sound generated by the sound generator 3 in accordance with an obstacle detection signal from an obstacle sensor 61 and a vehicle speed detection signal from a vehicle-speed sensor 62.
