The invention relates to a backlit motor vehicle gauge such as a speedometer or a revolution counter, which gauge has a wall provided with translucent graduations disposed over a circular arc, one or more light-emitting elements () carried by a support plate (), and a light guide () interposed between the support plate () and the graduated wall so as to diffuse the light emitted by the light-emitting elements () towards a back face of the graduated wall in order to illuminate all of the graduations. According to the invention, the light guide () is mounted to pivot IO about an axis (AX) passing through the center of the circular arc while having its position servo-controlled, and said light guide () carries a spot lighting member () situated radially at the same level as the circular arc so as to highlight a portion of the region carrying the graduations. The invention is applicable to gauges designed to equip motor vehicles.
