## 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: Easy to Use. Convenient. - I like this test light. It fits my budget and is easy to use. I like having the readout! The clamp for the ground wire makes life a lot easier instead of trying to hold a probe in each hand like a standard volt meter.
Review: Decent value for the money. - Seems like a decent little test lamp. Reads the voltage, which is a bonus. Green light voltage going in one direction, red light- reverse polarity. Decent length curly cord. You could spend a lot more for one that might last longer, but you can’t beat the price for this thing.
