Abstract
An illuminated instrument cluster utilizes a single light emitting diode to backlight the entire dial surface. The LED is aligned with a light guide then directs light into a cavity of a light housing. The cavity includes a surface that reflects light upwardly onto a back surface of the dial face to provide the desired illumination.
