とを特徴とする車両用点滅装置。A series circuit in which a fault means, a direction indicator switch, and a direction indicator light are connected in series from an on-board power supply, a current detection means for detecting the amount of current flowing in this series circuit, and an output generated in this current detection means is used as an input to detect the direction. a detection circuit that generates a first detection output when a rush current flows through the indicator light and generates a second detection output when at least one of the lamps constituting the direction indicator light is disconnected; a storage circuit that stores the detection output of No. 1 for a predetermined period of time; a switch determination circuit that is connected to a terminal of the direction indication switch and determines the state of the direction indication switch and generates a determination output when the direction indication switch is turned on; output and said first
The output of the memory circuit when the detection output is generated continues oscillation and drives the switch to open and close, and the oscillation period and the duty ratio of the opening/closing drive output are controlled by the second detection force. A flashing device for a vehicle, comprising: an oscillation circuit.
