ABSTRACT:
A gauge or dial has multiple displays for indicating various vehicle operating conditions. Pointers indicate a range of measured values on some of the displays. A fixed hub covers ends of the pointers where they connect with their drive shafts and extend through the dial. The hub has a display screen with a graphic or symbol imprinted on it. A conduit directly under the hub on an opposite side of the dial extends to a printed circuit board. A light emitting diode is mounted on the printed circuit board within the conduit. Light from the diode is reflected through the conduit to backlight the symbol on the display screen. Switching on and off of the diode is controlled in response to sensing or measurement of a vehicle condition or vehicle component operation, such as a turn signal.
