ABSTRACT:
A reflector provides different-colored backlighting to indicia and a background field of an instrument dial. The dial is mounted on a reflector, forming an interior space. The reflector is assembled on a printed circuit board (PCB). A recessed section of the reflector has an opening exposing a portion of the PCB to the interior space. Another section of the reflector provides a short tube having an inner cavity suspended over the opening. A first group of light emitting diodes is mounted on the exposed portion of the PCB under the tube such that light from the first group is reflected through the inner cavity to light a pointer. A second group of light emitting diodes having a different color is mounted outside the tube and backlights the indicia of the dial. A gap between the exposed portion of the PCB and an end of the tube enables light to leak from the inner cavity and backlight the background field of the dial a different color than the indicia.
