Review on 🚗 Mini Waterproof Voltmeter with Green LED Display, DC 12V-24V Voltage Meter Tester for Car Motorcycle Auto Truck Campervan by Greg Bellman

I bought this Green DC Voltage Meter for my 2004 Nissan Sentra 1.8S to monitor the battery voltage. I have a car audio system that drains my battery quickly when I play music without starting the car and this DC voltmeter works great. It's bright enough to read the display in direct sunlight, and not too bright at night to distract you from the green glow in your eyes while driving. I used a hole saw, cut a hole in the dash, hooked it up to a heavy duty switch and wired it up to power the buttons. Even if the switch is on, it doesn't get power until the key is on. . Worth every penny in my opinion and would recommend this product to anyone.
