Abstract: A circuit pack has a flat circuit board and a flat apertured face plate mounted at substantially right angles to the board. A plurality of light emitting diodes are surface mounted on the board and emit light at an angle to the axis of the apertures in the face plate. Mounted in each of the apertures is a light guiding member, one end of which overlies the corresponding diode and has a reflecting surface positioned in the path of light emitted from the diode to redirect the light through the aperture. Crush ribs on the surface of the light guiding member to aid in affixing it in the aperture.
