FIELD OBSERVABLE LIGHTING FOR AIRPORT SURFACE VEHICLES

WIPO Patent Application WO/2010/099531

A3

A warning light system for an airport vehicle has a warning light carried on a movable vehicle and a power controller linking the warning light to an electrical power source, selectively causing the electrical power to flow to the warning light such that the warning light illuminates and to interrupt flow of the electrical power to the warning light such that said warning light is not illuminated. Control circuitry connected with the power controller determines whether or not a geographical position of the vehicle indicated by a GPS receiver on it is within a predefined geographical area. Responsive to a determination that the vehicle is within the predefined geographical area, the control circuitry causes the power controller to illuminate the warning light. Responsive to a determination that the vehicle is not within the predefined geographical area, the control circuitry causes the power controller to interrupt flow of the electrical power to the warning light such that the warning light is off. The warning light as a result illuminates without any action by a user when the vehicle enters the predefined geographical area and is extinguished when the vehicle leaves the predetermined geographical area.
