The AEM Digital Voltmeter Gauge combines accuracy, speed, and control with an easy-to-read digital LED interface that displays voltage in 1-volt increments alongside a sweeping LED "needle" that lines the gauge edge and moves as voltage changes from 8 to 18V. The digital readout automatically increases and decreases brightness via a built-in ambient light-sensing photocell.
Specifications:
- 24 green LED display lights for immediate reference to monitored voltage
- Easy-to-install plug & play harness and sensor included
