Automotive Test Light with 3-48V LED Digital Voltage Display, Auto Circuit Tester with Voltmeter & Dual Color Polarity Indicate, Electric Test Pen w/Stainless Probe for Car/Truck/SUV Checker

Cord is long enough to reach across my Chevy Silverado from battery to fuse box-Extremely easy to use, great cost for the product. It is well made- and functions well (I have yet to see a green light they’re all red, but I’m a woman who doesn't know much lol and only uses it for fuses -). Fits right in the glove compartment and can be used at any time- works great for what we boogie it for.Would buy again !

Needed this to locate a parasitic leak in my classic Chevy. It works well, built quality is great and has a nice bright light plus is very accurate. Just throw this in your tool bag and when you’re needing to locate a constant or intermediate voltage on your old vehicle, this is the item to own.

This works very well. It has a coiled test wire that is quite long. It was used on a golf cart and read 49.4 volts of the battery pack perfectly.Very well priced too.

I really like these test lights. Unlike normal test lights that just light up when they find a wire with power, these will tell you the voltage on a little digital display. Polarity does not matter, if the + is at the clamp and the - at the probe, it still displays voltage, just in a negative number. Very useful for things like cabin fans in cars where they change the voltage for the different speeds. My only gripe is that they seem to only last 2-3 years. If they held up better, I would give this 5 stars. To be fair, I do a lot of work on farm tractors and the like, and I'm not exactly delicate with things all the time. Falling off the roof of a tractor cab is an easy 8-10 feet down onto concrete, which may be part of the problem. My friend has a $120 Snap ON that has been going for years, but for the money 2-3 years out of one of these is probably doing pretty good. For occasional use, and better handling they would probably last a long time.

Quick tested on a battery to confirm voltage works.Worked fine. Cord could be longer. But seems to be a good quality tool due the price.

Well worth the money and very handy for troubleshooting and wiring on your boat

I had an older Matco that prob older than I am that finally bit the dust. This product is lightweight, and not sure about longevity, but for the money, it is great. Really nice that it lights up red or green depending on polarity. And showing voltage means it does 90% of “quick electrical” vehicle repair tasks needed. 3v to 48v is nice. I’ll report fails, but I bought 3 and so far so good as of Feb ‘25.

Works great. Fast delivery.
