Abstract
An omni-directional taxiway light uses an axially symmetric conjugate lens pair to distribute lamp light, particularly substantially parallel to the taxiway surface, while protruding minimally above the surface. An associated fixture contains a housing holding the optical elements in fixed relative positions and a weather-proof seal arrangement.
