An aircraft light device has a base, a printed circuit board, a reflector and a cover-lens. The reflector is comprised of a number of reflective surfaces connected together to form a spline. Light transducers on the printed circuit board are of two main types, light emitters and light receivers. Light emitters provide light for illumination, while light receivers enable detection of received light. The two transducer types can be used alone or in combination.
