Abstract
A vehicle direction indication device is configured such that a voltage of a battery power supply is detected, and when a direction indication light switch is switched to ON, a pulse width modulated signal is output. This pulse width modulated signal is generated by pulse width modulating a flash signal for driving a direction indication light in a flashing manner with a duty ratio based upon the detected voltage of the battery power supply; the duty ratio at which the voltage of the battery power supply is high becomes smaller than that at which the voltage of the battery power supply is low. The direction indication light is then driven in the flashing manner based upon the output signal.
