ABSTRACT:
A light device including side emitting status indicators that provide a true indication of whether light is being output in a primary output direction. The light device includes a light source of at least one LED configured to generate light in the primary output direction. The light generated by the at least one LEDs passes through a lens device, that may also reflect a portion of the light generated from the at least one LED. Collection optics are provided to capture a portion of the generated light and/or the reflected portion of the light generated from the light source, and are configured to output the captured generated and/or reflected light in a direction other than the primary direction, i.e., in a direction for the side emitting status indicators.
