Abstract
A visual navigational aid for guiding the approach path of incoming aircrafts, ships or other vehicles. The visual navigational aid comprises high intensity light emitting diodes (LEDs) or LED arrays and optical beam shaping apparatus that produce multiple light beams with different colors or flash patterns to guide the incoming aircrafts, ships or other vehicles to a pre-determined approach path.
