Abstract
A self-contained accessory for an analog metering device such as a speedometer or tachometer. The accessory includes a sensor which is selectively adjustable to align with a plurality of positions in the range of movement of an output needle of the analog metering device. In the preferred embodiment, the sensor is alignable with gradation marks, e.g., miles per hour indicia on a speedometer, and the accessory provides a clear indication when a needle reaches a selected gradation. The indication alerts a user that a selected gradation has been reached by an output needle of the analog metering device. The accessory attaches to a cover of the analog metering device and allows adjustment of sensor position without removal of the accessory from the cover.
