AEM Voltmeter Display Gauge LBZ DF-200 is recommended for UltraAEM 30 4400 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.
