Abstract
An electronic flasher system that reduces the ON duty ratio of an intermittent signal inputted to a semiconductor switch device, thereby 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. The flasher system includes a flasher circuit 21A, a semiconductor switch device 21B, and a device-temperature detecting section 21C 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 a temperature of the semiconductor switch device 21B so that, when the temperature becomes high, the ON duty ratio of the intermittent signal is reduced.
