Abstract
An insert is installed at a corner and two adjacent edges of an enclosure for electronic equipment so that a signal light, such as an LED, may be observed from two sides of the enclosure. The insert has a prism to refract light in both directions from an LED or similar signal light supported on the insert in a fixed position relative to the prism. The corner of the prism is rounded to function as a lens. The corner of the enclosure is cut away at the upper edges of the converging sides and the cut-away area filled with the lens. An apron depending from the insert may be welded or otherwise adhered to the interior of the enclosure.
