Review on 💧 Waterproof DC 12V Car Digital Voltmeter Gauge with LED Display - Blue by Andy Hearshman

I have two of these and both still work. They both read the same as my Craftsman voltmeter. (I don't have a fluke) I think red digital light is easier to read in the sun. The other is blue and difficult to see in bright sunlight. He's on a quad, so the sun is shining directly on him. One thing I've noticed is that the readings will flash if they are below 12 volts. I'm not sure where it stops blinking. All I know is that my quad starts charging and stops blinking. (coming to 13.4) You can install it anywhere. Run some wires there, phew! You have voltage readings. Cozy!
