The AutoMeter red LED replacement bulb is made for Monster Tach pedestal units and some in-dash tachometers that use the small twist-in light on the front shield. It swaps in for 86-style wedge bulbs, draws 0.02 amps and provides low-level illumination for gauges. It will not work with the listed Digital and LED-lit AutoMeter gauge models.
