<p>Disclosed is an electronic flasher system which is adapted to reduce small the ON duty ratio of an intermittent signal, which is inputted to the semiconductor switch device, suppressing electric power imposed on the semiconductor switch device and hence heating thereof, in the event of abnormal heating caused in the semiconductor switch device due to a certain cause. A flasher circuit 21A, a semiconductor switch device 21B, and a device-temperature detecting section 21C are arranged in one body to constitute a module unit 21. The device-temperature detecting section 21C is connected to the flasher circuit 21A. The flasher circuit 21A transmits an intermittent signal to the semiconductor switch device 21B so that a direction indicator lamp 1R, 1L connected to the semiconductor switch device 21B is caused to turn-signal flash. The device-temperature detecting section 21C detects heated temperature of the semiconductor switch device 21B so that when the temperature becomes high the ON duty ratio is reduced small.</p> |
