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

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

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.

The volt meter is a good feature Only not good is comman test light issue with cord to stiff in cold weather

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

Very useful in diagnosing issues. clear to read display, as well as polarity settings, i bought one as a gift for a friend after I.Tested the first one. worth the money

Got it fast and I worked perfectly, thanks.

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