12 V 8-48 V LED voltmeter

The Nilight 90354A is a hard-wired digital voltmeter with a blue LED display and touch switch. It mounts in a 1.15" panel cut-out using a twist-lock fastener and supplied screws. The unit operates from 8 V to 48 V and shows real-time voltage or battery percentage. Fire-retardant PC housing gives waterproof and heat-resistant protection up to 100 °C.

Automotive marine and recreational vehicles

This gauge suits owners of cars boats motorcycles trucks and golf carts who want a permanent panel-mounted voltage monitor. The touch switch toggles display modes or turns the screen off to reduce parasitic draw during storage. Installers who need wireless connectivity or data logging should look elsewhere as the device provides only a local visual readout.

Operating voltage range 8 V to 48 V

The single specification that decides fitment is the 8 V minimum and 48 V maximum operating window. Any electrical system that stays within this range can power the meter directly without an external supply. Systems that drop below 8 V or exceed 48 V will not work with this unit.

Questions about this item

Should I pick the 8 V or 48 V version for my 12 V system?

There is only one version; it reads from 8 V up to 48 V, so a single unit covers 12 V automotive and marine installations.

What does the blue LED display actually show while the engine is running?

It shows real-time battery voltage and can toggle to a percentage readout; the touch switch also lets you blank the screen to cut parasitic draw.

How does the hard-wire connection limit where I can mount the gauge?

The gauge needs a permanent 12 V feed and ground, drill a 1.15" hole, then secure it with the supplied twist-lock fastener and two screws.
