2-1/16in D/P/S Shift Light - 1 Stage- Silver

The AUTOMETER 2-1/16in D/P/S Shift Light - 1 Stage- Silver is a compact single-stage engine management indicator designed for drivers who demand precision timing feedback during high-performance driving or racing. This shift light serves as a visual cue system, alerting operators when engine parameters reach pre-set thresholds without audible distraction. Whether you're running a modified street engine, competition vehicle, or monitoring critical shift points under load, this gauge provides the instantaneous visual feedback necessary to optimize shift timing and prevent over-revving.

Engineered by AUTOMETER—a recognized leader in precision instrumentation—this single-stage shift light features a 2-1/16-inch (52mm) diameter housing that integrates seamlessly into modern dashboard configurations. The silver finish complements both classic and contemporary gauge clusters while maintaining high visibility in varied lighting conditions. The one-stage activation design simplifies wiring and tuning compared to multi-stage variants, making it ideal for straightforward engine management setups. At just 0.5 lbs with compact dimensions of 7.6 x 3.55 x 8.55 inches, it installs cleanly without adding significant weight or bulk to the vehicle.

This shift light benefits motorsports enthusiasts, street rod builders, and drivers running aftermarket engine control units who need reliable RPM threshold indication. Installation requires connection to an appropriate trigger source—typically an ignition or tachometer signal—and is compatible with most electronic engine management systems. Users benefit from reduced reaction time during critical shift events, extending engine life by preventing inadvertent over-revving and optimizing power band utilization across acceleration runs. Professional installation is recommended to ensure proper signal calibration and secure mounting.
