Abstract
A visual signaling device which has a horizontally extending lamp which is connected to an electrical housing and which is surrounded by a reflector body. The reflector body has a pair of oppositely extending horizontal parabolic troughs and a downwardly extending horizontal trough. Each trough has an input opening adjacent the lamp, an output end opening, and a front opening. Each trough is defined by a generally planar back wall and a pair of opposed side walls. Each side wall is horizontal from the back wall to the front opening and parabolic relative to the central longitudinal axis of the lamp from the input opening to the output end opening. In a second embodiment of the invention, the reflector has an upwardly extending parabolic trough.
