ABN Wire Piercing Circuit Tester LED Test Light 6-12-24V – Automotive Probe Tool Electric Trailer Wiring Diagnosis

If you have ever stabbed your own finger trying to get a regular tester into a wire, you will appreciate the ABN Wire Piercing Circuit Tester.

This device identifies wiring issues such as short circuits, fuses, test connections, wiring harnesses, and more.

It can be used in the shop to check wires when installing radios and brake controllers, on your camper to test which wires operate the tail lights, or any trailer wiring application.

Unlike typical testers, the hook cover design prevents you from stabbing your own finger when placing the tester in a wire.

It can be used as a probe on its own by removing the plastic sleeve that hooks the cable or as a probe and hook that pierces the wire.
