Electronic flasher system
First Claim
1. An electronic flasher system, comprising:
- a flasher circuit for transmitting an intermittent signal;
direction indicator lamps arranged to provide a turn-signal flashing based on the intermittent signal from the flasher circuit;
a sound generator for generating a variable turn-signal operating sound based on the intermittent signal from the flasher circuit and corresponding to the turn-signal flashing of the direction indicator lamps; and
a sensor coupled with the flasher circuit for outputting an output signal depending on an operating state of a vehicle, wherein the turn-signal operating sound changes in accordance with the output signal from said sensor.

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.
