Abstract

PURPOSE:To accurately detect shortcircuit by detecting the shortcircuit of a flasher using the timing abstracted from the flashing control pulses and cutting off current paths. CONSTITUTION:Power is fed to the control circuit 3 from the battery 1 loaded on a car through the key switch 2 and current supply signals are intermittently applied to the direction indicating flashers 4a and 4b through this control circuit 3. The voltage of the resistor 9 which detects the current applied in the flashers 4a and 4b is applied to the shortcircuit detection circuit 16 and the intermittence detection circuit 17. The detection circuits 16 and 17 check for shortcircuit and disconnection whenever the changeover switch 6 turns on and the result is notified drivers by way of the display lamps 22 and 23.
