Key features

• •🚘 High Security: The professional auto circuit tester has a built-in circuit board chip, which is safer and more durable than traditional test lights and prevents the car computer board from burning out. Anti-bending design of the tail wire, no need to worry about bad contact of the line.
• •🚘 Bidirectional Voltage Testing: This upgrade circuit test light is a bidirectional voltage tester. You can attach the alligator clamp either to negative or positive ground, there is also a light emitting diode on the circuit board for polarity indication, red light indicates positive polarity and green light indicates negative polarity.
• •🚘 Unique Design: Adopt the integrated structure design of the probe protection cover, needle guard function is added to ensure that there will be no stab wounds and the guard will not be lost. Convenient to carry and take it wherever you go.
• •🚘 Wide Application: Professional automotive circuit tester/circuit test light with 3-24V DC voltage testing range, ideal for checking various vehicles electrical circuits, quickly check automotive headlights, taillights, turn signal circuits, faulty sockets, fuse connections, also for testing other 3-24v DC wirings and circuits.
• •🚘 Easy to Use: High quality 70.8 inches long enough PU spring wire offers more flexibility, lighter and more durable than normal cable wires, convenient for use and storage, along with large size alligator clip for easy one hand operation, will definitely improve your working efficiency.
