Abstract: A multiple function, multiple digit meter includes a light directing structure (18) for providing uniform illumination to digits (14) of display (12). A block (20) of clear plexiglass has a surface (22) facing the display (12). Edges (24, 26) of the block (20) have notches (27, 28) for receiving incandescent bulbs (30) to direct light into the block (20). The block (20) has a back surface (32) which curves upward moving away from the bulbs (30) toward the center (34) of the block (20). Surface (32) is reflective to direct light toward the display (12). The configuration of the surface (32) causes an increasing percentage of light received at the surface (32) from the lamps (30) to be reflected toward the display (12), with increasing distance from each lamp (30). The panel meter (40) has a first manually actuated means (70) for selecting one of the multiple functions of the meter (40) and a second manually actuated means (72) for changing a displayed value of a selected function.
