led digital test light

Works as designed, easy to use and accurate. Love the voltage display as it takes the mystery out of knowing exactly what the voltage is rather than just a lit bulb.

Nice and simple...will come in handy for automotive and small solar power setup.

Hooked up to my automobile battery to test it and it worked great. Bright and easy to read. Showed volts and I'm really happy with this purchase.

A very useful tool. Does two jobs at once. Tells that there is active power and what the voltage is between the two points.

Great test light. Shows battery voltage and alternator output.

This probe is superb. It works very well and the digital readout aids in troubleshooting circuits. I default to this probe whenever an electrical system issue pops up.

I think it says something about a product when in reality you know nearly nothing about how to use it, yet you still can because it's that simple and easy to use. This is one of those products. I decided to hardwire a dashcam in my car. I know literally nothing about installing electronics. When it comes to electricity and installing things, I usually leave it up to my mechanic father-in-law, as I'm convinced that my phobia of being electrocuted is some Lamarckian feature inherited because my great grandfather was electrocuted in 1909. I'm not joking. So against my better judgment I decided to take on this task, and let me tell you: it was way simpler than I'd ever imagined, in part thanks to the AWBLIN Circuit Tester. I watched some installation videos and many of them had the normal circuit tester that simply has a lightbulb in it that lights up. But because the installation directions specifically said to choose a fuse with at least 12v, I wanted to get this one since it will show you that information. In fact, it can display and alert you to a lot more information than just that, if you really need it. But I just needed the voltage, and it accurately displayed it each time. It's very simple to use and comes with clear directions. Really, you probably won't need them because the display is so clear and easy to use. And, at this price versus the simpler version, it just makes sense to get this version. You don't get just a lightbulb that essentially says "there's power!" but rather you get all sorts of other information that can be useful for your task. I highly recommend this circuit tester. If someone as apprehensive about electricity like me can use it perfectly, you can, too, and for those of you who have a lot more experience with this stuff, this circuit tester displays all the information you could ever want.

It’s perfect for now looks like quality workmanship

Es un acceorio muy practico y con lecturas de voltaje CC de alta exactitud.

A tool for every DIYer’s toolbox. It is like carrying a mini multimeter with you. Quick for doing diagnosis on battery state of charge, charging system voltage, identifying polarity of circuits etc.

Good tester. Like the LED for battery quick check

works great

sturdy and works well, no complaints
