Abstract
An electronic range indicator apparatus in which a switch array powered by the vehicle ignition voltage is used to indicate the selected transmission range during both on and off periods of the vehicle. During on periods of the vehicle, the ignition voltage is transmitted through the closed contacts (if any) of the switch array, and a decoder/driver module decodes the output of the switch array and lights the indicator indicia corresponding to the selected range. During off periods of the vehicle, the ignition feed to the switch array is open circuited. In such case, the decoder/driver module effectively grounds the ignition feed of the switch array, and lights the appropriate indicator indicia using an inverse logic decode scheme.
