ABSTRACT:
An improved apparatus for use in the turn-direction indicating system of a vehicle having at least front and rear directional lamps. The directional lamps are connected in parallel with each other to be energized by a battery through a current detecting resistor, a relay and a direction selecting switch. The relay is energized to close periodically in response to periodic pulse so that the directional lamps flash periodically. Generation of the periodic pulses is controlled in response to the voltages appeared across the current detecting resistor and at the junction between the relay and the direction indicating switch. The relay is adapted to function as an alarm buzzer for informing the disconnection of both front and rear directional lamps.
