12V Circuit Tester Probe 3-48v Electric Car Fuse Test Light Voltage Pen Detector

Features: 1.LED Digital Display: Accurate Reading Power Circuit Probe Kit is designed with LED digital voltage display, which can read the voltage accurately. Bidirectional current and voltage test mode, the alligator clip can be connected to the negative pole or the positive pole to ground, the red light means the positive pole, and the green light means the negative pole. Compared to LCDs, LED lights are not affected by the brightness of the light and can be read accurately in day or dark areas. 2. Negative clip protection: Equipped with pure copper clips and insulating protective cover, which can better clamp the body and screws, insulating protection against electric shock. The circuit board has line protection function, which is safer and more resistant to burning. 3. Widely used: This professional automotive heavy duty circuit test light is designed to test 3-48V DC voltage. Can be used to detect power, ground, and find shorts and breaks in wires. Quickly check car headlights, taillights, turn signal circuits, faulty sockets, connections, fuses, broken wires, and more. 4. High quality product: The handle of the DC circuit tester is made of AS plastic, hardened and tempered carbon steel probe is chrome plated. Sharp steel probe easily pierces wire insulation to inspect circuits
