Claims

[Scope of utility model registration request]

A contact point connected to the direction indicator lamp group via a direction indicator switch is opened and closed by a relay in a charging/discharging circuit including a capacitor to cause the direction indicator lamp group to blink, and one of the direction indicator lamp groups is In the flashing circuit, the load current that decreases due to the disconnection of one or more lamps is detected by a current detection resistor and the opening/closing cycle of the contacts is changed, and the terminal voltage of the capacitor is charged and discharged by opening/closing the contacts. a first transistor that is controlled by a controller to conduct and interrupt conduction to excite and demagnetize the relay; and a second transistor that conducts and increases the terminal voltage of the capacitor when the load current flowing through the current detection resistor becomes equal to or less than a predetermined value. A blinking circuit characterized by comprising two transistors.
