This automotive circuit tester is equipped with a bright LED digital voltage display that delivers accurate and dependable readings. Compared with traditional LCD test lights, the LED screen remains clearly visible regardless of lighting conditions, ensuring easy reading in sunlight or low-light engine bays.
Featuring a highly elastic spring wire that extends up to 110 inches, this tester provides added reach and flexibility during inspections. The reinforced anti-bend tail wire helps maintain stable contact, while the oversized alligator clip allows safe and convenient one-handed operation.
The built-in dual-color LED indicator makes polarity identification simple. A red light signals positive polarity, while a green light indicates negative polarity. The clip can be attached to either terminal, allowing easy probing of the opposite side.
This upgraded circuit tester includes an integrated circuit board for improved durability and safety compared to standard test lights. The insulated housing offers a comfortable grip while reducing shock risk, and built-in line protection improves heat resistance and operational safety.
Designed for a wide range of automotive testing tasks, this circuit tester pen is suitable for diagnosing headlights, brake lights, turn signals, fuses, sockets, wiring faults, and loose connections. The sharp, extended probe easily accesses tight or hard-to-reach areas.
