Abstract
An automotive gauge has a two part housing containing a stepper motor arrangement or other gauge movement which drives a pointer shaft. The front housing part consists of a transparent material for conducting light from a lamp to a facet which reflects light to a pointer for pointer illumination. The lamp is mounted inside or outside the housing. The front housing part includes an aperture for accommodating the pointer shaft and also has integral pins which serve as supports for rotary parts of the mechanism. The housing is mounted on a circuit board or a circuit board may comprise the rear housing part. Another embodiment uses a common light pipe member for the front housing of several gauges.
