Product Description

Wide Testing Range (3-72V)
The JASTIND premium automotive test light offers an expanded voltage range of 3-72V, surpassing most test lights available. Ideal for checking a variety of automotive electrical circuits—such as headlights, taillights, fuses, and batteries—this versatile tool is also suitable for other 3-72V DC circuit systems.

LED Digital Display & Auxiliary Lighting
Our heavy-duty auto circuit light tester features an LED digital display with a voltage reading resolution of 0.1V, ensuring high accuracy within ±0.2V. The clear digital readouts are easy to read both day and night. Additionally, two LED beads illuminate the circuit area being tested, enhancing visibility during night-time work.

Bidirectional Voltage Testing & Computer Safe
This bidirectional voltage tester includes two color LED lights and a buzzer for polarity indication. When the clamp is attached to the ground or positive terminal, the red LED light turns on and the buzzer sounds once for positive voltage; the green LED light activates and the buzzer sounds twice for negative voltage. The precision-designed circuit board generates a much smaller current than typical test lights, significantly reducing the risk of damaging central computer boards.

Anti-Lost Probe Protective Tip & Quality Tester Body
The sharp stainless steel probe pierces wires with ease and reaches into tight spaces. It features a specially designed anti-lost protective cover that ensures safety by preventing accidental stabbings and guarantees the probe won’t be misplaced. The tester includes a maximum 142-inch spring wire with an anti-tensile PU outer skin and high-conductivity copper inner wire, which recovers automatically after stretching, making it both convenient to use and store.
