A display system includes a liquid crystal display, a light guide behind the display, and light emitting diodes. The light guide is a molded slab of clear material with a front display surface a rear surface and six bordering surfaces with two planes depressed into its rear surface and having two hollow half cylindrical extensions integrally molded with closed top and bottom ends.

These extensions receive light from surface mounted LED's which are positioned directly below the extensions to redirect the light into the light guide.
