⚡ Know the Voltage Instantly
The built-in LED display gives you an actual voltage reading instead of relying on a simple test-light glow. Bright digital numbers stay easy to read in both daylight and darker working areas.
🔴🟢 Find Polarity in Seconds
No more second-guessing positive and negative connections. Red indicates positive polarity, while green indicates negative polarity, helping make circuit checks faster and easier.
🔧 Reach More Without Repositioning
The 106.3-inch coiled lead gives you plenty of working room around the vehicle. Pair it with the large alligator clip and sharp stainless steel probe to reach wires, terminals, and tight spaces more easily.
Why Choose Our Diagnostic Probe?
Unlike a basic test light that only tells you whether power is present, our Diagnostic Probe gives you the information you need to troubleshoot faster. Get instant digital voltage readings, identify polarity at a glance, and test 5–90V DC systems with an extended coiled lead designed to reach across the vehicle.

Works As Advertised
Works exactly as described. Measures voltage and negative and positive currents. The quality is decent and you really can't beat the price, as it's a very helpful tool to keep in your vehicle.

Good product
I found the problem thanks to this product. Fuses were fine but not enough voltage was getting to them. I turned out to be a faulty old ignition switch.

Very capable digital readout test light
I am a Vine reviewer who actually opens the box, really tests, really evaluates, and writes really honest unbiased reviews of products. I don't have a whole lot to add to the other excellent reviews. I tested this test light in a variety of scenarios and it worked very well. Most of the time the reading was .1V DC less than a couple of DMM's I was using, and also a solar charge controller that also had a digital readout. I don't consider .1V discrepancy to be a big deal when using a test light. As long as it is that close (.1V or so) I'm perfectly fine with that. Beats just having a "test light" that merely lights up. Coiled wire has nice stretch to it and recoils nicely. Clamps work well. Digital readout is nice and bright. Point is sharp. Recommended.
❓ Frequently Asked Questions
What voltage range can it test?
What voltage range can it test?
It is designed for 5–90V DC electrical systems.
What vehicles can I use it on?
What vehicles can I use it on?
It can be used on compatible DC circuits in cars, trucks, motorcycles, golf carts, boats, and other vehicles within its specified voltage range.
Can it tell positive from negative?
Can it tell positive from negative?
Yes. The polarity indicator displays red for positive (+) and green for negative (–).
What can I troubleshoot with it?
What can I troubleshoot with it?
It's designed for quickly checking components such as batteries, fuses, headlights, taillights, turn signals, sockets, and damaged wiring.
Is this the same as a multimeter?
Is this the same as a multimeter?
No. It's a fast automotive circuit-testing probe designed primarily for voltage and polarity checks. A full multimeter remains more appropriate when you need additional measurements such as resistance or current.
