The AEM Digital Voltmeter Gauge combines unsurpassed accuracy, speed and control with an easy-to-read digital LED interface that displays voltage in 1-volt increments, and a sweeping LED "needle" that lines the edge and moves as voltage changes from 8 to 18v. The voltmeter gauge's digital readout will automatically increase and decrease in intensity due to the built-in ambient light sensing photocell.

Each gauge includes interchangeable silver and black bezels and black and white faceplates to personalize the look of your gauge.
