To provide a direction indicating apparatus that is less susceptible to a change of a power supply voltage and can reduce the difference in brightness of a direction indicating lamp using an LED element between a direction indicating operation and a hazard operation. A direction indicating apparatus includes a pulse signal generating part (4), a first switching element (NM1), a variable resistor circuit (5), a direction indicating switch (SW1), a hazard switch (SW2), first and second direction indicating lamps (2L and 2R), a voltage detecting part (6) and a lighting status detecting part (7). The lighting status detecting part detects the lighting statuses of the first direction indicating lamp and the second direction indicating lamp, switches the resistance of the variable resistor circuit to a second resistance when both the first direction indicating lamp and the second direction indicating lamp are turned on and switches the resistance of the variable resistor circuit to a first resistance when any of the first direction indicating lamp and the second direction indicating lamp is turned on.
