## Description

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: desertcart.com: Tools & Home Improvement

Review: Great Tool! - 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.
Review: Lot of good uses for a good price. - 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 .
