Dimensions: 230 mm, Cable Length: 255 mm

Material: Plastic + Metal

Accurate LED Digital Display: The circuit tester in this probe kit features a digital LED voltage display for accurate measurements. Measurement Range: 3-48 V DC.

Bidirectional Current and Voltage Testing Mode: You can connect the alligator clips to either negative or positive ground; the red LED indicates the positive terminal and the green LED the negative terminal. Get accurate measurements day or night.

Safe and Durable: This high-performance automotive circuit tester features pure copper terminals and insulated protective covers for a tighter fit of the housing and screws, ensuring insulation protection and preventing electric shock.

The circuit board is protected for added safety and burn resistance.

Easy to use: Connect the alligator clips to ground, then use the probes to test the circuit. The sharp steel probes easily penetrate insulation to inspect circuits, locate broken wires and current flow, and quickly and easily check fuses, lamp sockets, and current flow.

Versatile: Use it to test current and ground, and locate short circuits and broken wires. Quickly check headlights, taillights, turn signal circuits, faulty sockets, connectors, fuses, broken wires, etc.
