This automotive test light works exactly as expected and makes diagnosing electrical issues much easier. The digital voltage display is clear and accurate, and the dual-color polarity indicator is really helpful for quick testing. The probe feels sturdy and well made, and the long cable gives plenty of reach around the vehicle. Great tool to keep in the garage or toolbox for car and truck work!

This circuit tester works great and is really easy to use. The lights clearly show positive and negative polarity, which makes checking things quick and simple. I’ve used it to test wiring and battery voltage on my vehicles and it’s been very handy. The long spring wire and big alligator clip make it easy to reach around the engine bay, and the sharp probe helps get into tight spots. Solid little tool to have around if you work on your own vehicles.

Fácil de usar, específico en cuanto a la polaridad de la corriente (verde o rojo) y sobre todo indica el voltaje que llega al punto donde se prueba.
