ABSTRACT:
A dual direction indicator including a plurality of lights arranged in opposed arrowhead configurations and an arrow shaft common to both arrowheads. In one mode of operation, the lights forming the arrow shaft and then the lights forming one of the arrowheads are sequentially energized to indicate one of two opposed directions. In a second mode of operation, the lights forming the arrow shaft remain energized and the lights forming the two arrowheads are alternately energized to indicate both opposed directions. The above is achieved in a simple, efficient, and inexpensive manner utilizing a plurality of relays and switches, a flasher, and a sequential motor switch.
