Abstract
A warning light having a wide angle radiation pattern and the ability to accept either an incandescent lamp or gaseous discharge tube as the light source is disclosed. The wide angle radiation pattern is, in part, achieved through the use a reflector having three separate surfaces which define parabolas with different axes and a common focal point, two of these parabolic reflector surfaces being spacially separated from one another and extending from the third reflective surface. The light emitter is supported from the third parabolic reflector surface such that the lamp filament or the gaseous discharge tube will extend through the common focal point.
