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

A very simple tool that picks up on voltage quite easily. The length of the wire is well sized for most cases. My only complaint is that the rubber warp on the handles of the ground prong managed to work their way off rather quickly, but that didn't affect the functionality of the tool. Definitely worth the price point and has helped me diagnose many automotive electrical problems.

Great basic tester just to check for voltage, works great to tell you the voltage of a battery (even 9V batteries) , will read out voltage of a car battery standing or running, helps determian if battery or the alternator is not good .

Not only check continuity but also determine the automotive line voltage. East to read, simple, and neat

This automotive test light is very handy and easy to use. The digital LED display is clear and makes it simple to read the voltage at a glance. I also like the dual-color polarity indicator, which helps quickly identify positive and negative connections. It feels solid and works well for basic automotive electrical checks. The probe is sharp enough to test circuits easily. The only reason I gave four stars instead of five is that the cable could be a bit longer. Overall, it’s a useful tool and a good value for the price.

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.

Works great. Only needed a few times, but these save a ton of time in diagnosis

Easy to use and accurate. Easy to read.

Muy prácticos
