AWBLIN Automotive Test Light Probe Kit 3–72V DC, 18-Piece LED Polarity Tester with Carry Case

The AWBLIN Test Light Probe Kit is an 18-piece, compact automotive circuit tester that checks 3–72V DC systems with LED polarity indication and a durable carrying case.

This kit bundles a digital-style LED test light with a full set of interchangeable terminals and accessories so you can probe vehicle wiring, fuses, batteries and small DC systems without juggling loose parts. The tester supports bidirectional voltage checks, includes male and female flat and round plugs in multiple sizes, two probe tips and an alligator clip, and stores everything in a foam-lined hard plastic case for tidy transport and quick access.

How does the AWBLIN kit help find electrical faults quickly?

The tester's LED indicator and wide 3–72V range let you identify live circuits and polarity fast on most cars and light vehicles. You can trace power, confirm ground, and test continuity points without disassembling harnesses.

• 3–72V DC range covers most automotive and small DC systems
• LED colors indicate polarity: red for positive, green for negative
• Interchangeable plugs let you connect to various terminal types
• Two probe tips for precise contact in tight connectors

What connectors and accessories are included in the set?

The kit contains 18 pieces designed to adapt the test light to many connector shapes and sizes. Everything nests into a molded foam insert so parts stay organized and ready for the next job.

• One AWBLIN automotive LED test light
• Seven male plugs (flat and round) in assorted sizes
• Seven female plugs (flat and round) in assorted sizes
• Two probe tips and one alligator clip for temporary grounding or power

Can I use this tester safely on both positive and negative ground systems?

Yes — the AWBLIN tester is bidirectional, allowing the alligator clip to attach to either ground or positive, while the LED polarity indicator shows which side is live. This reduces guesswork when working on vehicles with different grounding schemes.

• Alligator clip connects to negative or positive as needed
• LED polarity display helps prevent reversed connections
• Low-profile probe tips allow safer contact in confined areas

How portable and durable is the kit for field work?

Designed for mechanics and DIYers on the go, the lightweight plastic case keeps the 0.55 kg kit compact and protected. The snap-close box and foam cutouts prevent lost pieces and make the set easy to toss in a toolbox or glove compartment.

• Rigid carrying case with built-in foam organizer
• Compact footprint for mobile repairs and roadside checks
• Sturdy plastic construction protects accessories from damage

Who is this for: The AWBLIN Test Light Probe Kit is aimed at automotive technicians, hobbyist mechanics, electricians working on low-voltage DC systems, and anyone who needs a reliable, portable tool for diagnosing vehicle wiring, fuses, lighting circuits and batteries. It’s especially useful for people who prefer a complete, organized set of connector adapters and simple LED feedback for quick troubleshooting.
