ATOBLIN Test Light Automotive 3-120V DC LED Digital Circuit Tester

ATOBLIN Test Light Automotive 3-120V DC LED Digital Circuit Tester helps you quickly verify car electrical circuits with a bidirectional voltage display.

Use this auto electrical tester to check automotive headlights, taillights, turn signals, sockets, fuse connections, and other 3-120V DC wirings and circuits in cars, trucks, and motorcycles. The compact probe provides a quick, visual assessment of circuit status, helping you identify faults fast during maintenance, roadside checks, or workshop diagnostics. Its clear readings support polarity confirmation and continuity checks without requiring a multimeter, making it a practical companion for routine electrical troubleshooting and preventive maintenance.

LED indication supports bidirectional voltage testing with a polarity display, where red indicates positive polarity and green indicates negative polarity, so you can interpret results at a glance in cramped engine bays or dim environments. The device's LED display adds reliability when testing in tight spaces, and the integrated design reduces the need for multiple tools. This makes it suitable for quick diagnostics on fuses, sockets, and wiring paths, helping you verify that connections are correctly established before repair or replacement.

The anti-lost needle guard protection design helps prevent injuries and keeps the guard with the tool, while a built-in circuit board chip enables computer-safe operation protecting vehicle ECUs and electronics during testing. A flexible spring wire extends up to 96 inches, offering broad reach and consistent contact across different test points while maintaining durability and minimizing stray contact.
