Abstract

The present invention is directed to a signaling device that incorporates a plurality of light emitting diodes and refractive clamp/optics which partially deviates and focuses the radiated light, an outer optic, which centers the beam on the horizon and determines the final vertical divergence, and a means of powering and controlling the device. The means for powering the device is any suitable power source.

Claims
