Claims

[Scope of utility model registration request]

One end of the blinker is connected to the power supply via the power switch, one end is connected to the direction indicator light via the direction indicator switch, and the other end is connected to ground, and the direction indicator light is activated for a time determined by the time constant of the charging/discharging circuit including the capacitor. In a flashing device that flashes
It detects the closing of the direction indicator switch and conducts it, supplies a charging current to the capacitor, and repeats conduction and cutoff depending on the charging potential of the capacitor, excitation and demagnetization of the relay connected to the collector, and the normal state of the relay. an inverting transistor that opens and closes an open contact, a first transistor that repeats conduction and disconnection by conduction and disconnection of the inversion transistor, and forms a charging circuit for the capacitor and determines the charging potential of the capacitor; A second transistor that detects the load current with a voltage detection resistor, repeats conduction and cutoff, and cooperates with the first transistor to determine the charging potential of the capacitor when the discharge potential of the capacitor and the direction indicator light are disconnected. A vehicular direction indicator light flashing device characterized by comprising:
