WINAMOO 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

I worked for Cummins Ct for 45 years I wish I had one then. A test light only shows if power is present. This shows if power is present and how much, it is a great bargain saves hooking up multi meter. I have told others don’t wait buy one

Works great! No need to drag out the multi-meter for simple automotive testing. Shows voltage up to ~40 volts DC, with green light to indicate correct current flow, or red for reverse. Has ~8 in long insulated probe, with ~3 ft spring cord with an attached alligator clip that allows a relatively large area for testing without resetting the clip. Read-out is bright and easy. Can't confirm reliability, only had it for a month, but appears to be fairly robust. Only cons, the cord while not flinmsey by any means, is not as "stretchy" as I would like, but I suspect this will clear up with use. Also the alligator clip could be larger to facilitate easier clipping to bolts for better ground,(I know, being picky). Due to being 10 - 12 inches long plus the spring cord, this tester is definitely not shirt-pocket friendly, but I would definitely recommend it.

like it alot. works great. cord is nice and long also.

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.

Works good and it’s tough. Been through the elements and still good.

Works, shows voltage and also the light comes on. Perfect for troubleshooting.

I use this all the time for quick voltage checks. It's easy to read and accurate, and can be hooked to the positive or ground side of a circuit, red LED indicates power and green LED indicates ground. The clip could be better and because of it's construction it is possible for the circuit board and display to rotate inside the housing when you're trying to reposition it, but for the price this is a great voltmeter test light and I really like how the rubber cap for the probe is attached to the cord.

Works really well very impressed with the quality

Muy prácticos
