Upgraded 3-72V Buzzer Automotive Test Light, Heavy Duty Digital LED Circuit Tester with Voltmeter and Dual Color Polarity Indicate Light, Bidirectional DC Voltage Tester Electric Light Test Pen

I really like this dc voltage tester. I have several different digital volt ohm meters and all sorts of voltage testers. I like this one for use on automotive and tractor electrical systems. Simple to use. The probe has a nice sharp point to penetrate wire insulation. Easy to read digital display. I’m very happy with it.

I use this all the time. I’m a flatbed trucker and especially in the winter you’re always having wiring issues. It works great for that or even having a short or bad ground you can basically spot the issue quickly with the volt meter built in.

Good quality wire and sturdy housing. Love the sound feedback function.

The only problem I have is the fact that the red LED comes on during correct polarity, and the green LED comes on with reverse polarity. I corrected this by desoldering the two LEDs, and switching them. Other than that, a very good, robust test light with voltmeter!

This light works great. I light the way it not only shows power but the voltage and whether you are checking negative ground or positive ground.

WORKS GOOD

Works great,a great tool to have
