ABSTRACT:
A system for controlling navigation lights and flashing anti-collision lights in the wing tips of an airplane, including a switch and circuitry constituting means for turning the anti-collision lights on and off from the cockpit of the plane without interfering with the normal operation of the navigation lights. The system functions using only a single wire to each wing tip, thereby obviating the need to install additional wiring inside the aircraft wings and fuselage.
