AWBLIN 4-75V DC Automotive Test Light

The AWBLIN 4-75V DC Automotive Test Light is a new heavy-duty circuit tester designed for automotive electrical diagnostics. It combines an LCD digital voltmeter with polarity indication and illuminating lights, allowing technicians and DIY users to check voltage, identify positive or negative circuits, and test fuses across a wide range of vehicles.

LCD Backlit Display and Extended Spring Wire

The tester features an LCD backlit digital display paired with red and green LED indicators for clear voltage reading and instant polarity identification in low light. A high-quality spring wire stretches up to 141.74 inches, enabling front-to-rear vehicle testing without moving the ground connection, while an integrated anti-lost probe cover protects the tip during storage and transport.

Overload Protection with Audible Alarm

Built-in overload protection triggers a buzzer alarm and displays "OL" on the LCD when voltage exceeds 75V DC, while the red LED illuminates to warn the user to stop testing immediately. This safety feature prevents damage to the tool and the vehicle's electrical system. The tool is not suited for technicians requiring AC voltage measurement or testing circuits above the stated DC limit.

Questions about this item

What DC voltage range does the AWBLIN tester measure, and what happens above 75 V?

It reads 4-75 V DC; above 75 V the LCD shows OL, the red LED lights, and a buzzer sounds to stop testing.

How far can the spring wire stretch for reach across a vehicle?

The spring wire extends to 141.74 inches, letting you probe from the front to the rear without moving the ground point.

How is the probe cover designed to stay attached during use?

An integrated anti-lost cover locks onto the probe so it cannot fall off or cause puncture wounds when stored.
