ABSTRACT:
A simple fuel consumption efficiency gauge employs a pointer mechanically coupled to the extremity of a Bourdon gauge. The pointer is electrically coupled to vehicle ground and is bracketed by two contact posts associated with high and low fuel consumption efficiency, respectively. Contact by the pointer with either post completes an electrical circuit through a corresponding light emitting diode to signal good or poor fuel consumption efficiency. When the pointer is between the contact posts, current is continuously supplied to another light emitting diode through a load in order to signal fair fuel consumption efficiency. The device is housed in a casing adapted for connection to similar casings by means of clips and clamps.
