[Problem to be Solved] To reliably maintain a hazard operation when an ignition switch is turned off during the hazard operation. [Solution] A direction indicator system 1 includes an ignition switch 3, a hazard switch 4, a direction indicator switch 5, direction indicator lamps 6A and 6B, direction indicator lamps 7A and 7B, and a direction indicator device 2. The direction indicator device 2 detects that the hazard switch 4 is in an ON state via direction indicator lamp connection terminals L-SW and R-SW, performs a hazard operation to blink both the direction indicator lamps 6A and 6B and the direction indicator lamps 7A and 7B by a drive current output from a drive current output terminal LOAD with a blinking period T in a case where the ignition switch 3 is in the ON state when the hazard switch 4 is put into the ON state, and operates with a voltage supplied from a battery connection terminal BAT1 to output the drive current when the ignition switch 3 is put into an OFF state during the hazard operation.
