allsun Auto Audible Circuit Tester, Car 6-12V DC Wire Piercing Cord Voltage Test Light Heavy Duty,Vehicle Circuit Low DC Voltage Light Tester,Hook Probe 59 in-Long Cord Sharp Stainless

This Automotive Audible Circuit Tester is a heavy-duty, 59-inch cord with a sharp stainless electric pen light and buzzer that is helpful in identifying problems and installing aftermarket components. The LED lights and audio tone are great features. One customer mentioned that they wish it had a zipper pouch to keep all detachable pieces together, while another found it too long to use while crawling under a dashboard. Another downside was that the hook tip was too thick for testing tiny wires. It is a good tester for occasional use and a go-to unit for both professionals and do-it-yourselfers.
