Abstract
A light, such as for an airport taxiway, in which a base includes a light source which outputs light. The light source may be an LED (light emitting diode) light source which is highly energy efficient and which has a long life. A light guide receives and guides light output from the light source. The light guide further extends out from the light source. A reflector is positioned in the light guide and reflects the light guided through the light guide to provide the appropriate illumination.
