Designed for professional-grade automotive diagnostics, it safeguards your vehicle’s computer while delivering precise voltage readings and polarity indicators, making it an essential tool for millennial managers who demand efficiency and reliability.

## Description

1.With LED digital voltage display, it can read the voltage value accurately even in dark environment.2.Mainly used for testing 6-24V DC voltage. It is often used for testing power, grounding and finding short and broken circuits.3.Connect the clip to the negative or positive ground wire, red light means positive, green light means negative.4. The spring-loaded wire stretches freely up to 79 inches for a wide measurement area.5.Package: 1 x voltage test pen.

## Features

- Unique Design: Anti-lost needle guard protection, the overall structural design of the probe protective cover is used to increase the needle protection function to ensure that there will be no stabbing and loss protection. Convenient to carry and take it wherever you go.
- Bidirectional Testing Mode: This upgrade circuit test light is a bidirectional voltage tester, attach the clamp either to negative or positive ground, the light emitting diode on the circuit board for polarity indication, red light indicates positive polarity and green light indicates negative polarity.
- Computer Safe: Equipped with insulation protective cover，which can better grip the body and screws, it has a built-in circuit board chip, which is safer and more durable than traditional test lights and prevents the car computer board from burning out. It can be freely stretched up to 79 inches, with a wide measuring area.
- Widely Use: his Professional automotive heavy duty circuit test light designed to test 6-24V DC voltage. Can be used to detect power, ground and find shorts and breaks in the wires. Quickly check car headlights, taillights, turning signal circuits, socket failures, connections, fuses, disconnection, etc.
- LED Digital Reading: The Power Circuit Probe Kit designed with LED digital voltage display for accurate volt readouts. Compared with LCD, LED lights are not affected by light brightness, and can be read accurately in daytime or dark areas. The built-in LED circuit board chip is safer and more durable than the traditional test light for the automotive computer board.

## Customer Reviews

### ⭐⭐⭐⭐⭐ I love the digital display
*by C***Y on April 17, 2023*

Easy to use, even with one hand. Strong clip, long cord. Very handy on my boat. I think I’ll get another for my car!

### ⭐⭐⭐⭐⭐ It works

Works as it should, great price and fast shipping

### ⭐⭐⭐⭐ Works well, better after modification
*by E***. on May 4, 2023*

Big Clive did a review and teardown of this model test light on YouTube. I figured I'd get it because his review looked decent.A couple things-I added a length of heat shrink to the probe so only about 1/2" of the point is exposed. This is to help reduce the risk of shorting out what I'm testing to ground. I suggest this, for sure.The circuit board fits loosely in the handle. There's nothing keeping it straight in the tube. I cut n opening in a piece of heat shrink tubing and put it around the board... Now it fits snug, but I had to add a small spring between the board and the connection in the tube. Works well and sits straight now. Thinking about it now, I could have put two small loops of heat shrink (one on either end of the board) and I probably wouldn't have needed to add the small spring.Also (as per Big Clive's suggestion) I reversed the diode so it's green when polarity is correct, and red when it is reversed. Makes more sense that way. I also added a small piece of heat shrink around the diode to subdue it. The green is really bright.In the description it says 6-24v, but I am able to read down to about 3.2v accurately. Below that it starts to fade and bounce around. I assume it is because the microchip needs 3v to operate. I haven't tested the upper range because I don't want to kill it. I like this little thing.In the description (as well as in the images) it says it can read the voltage in forward and reverse polarity. The one I received does not. It only displays a voltage reading when the clip is negative and the probe is positive. This may be an issue in certain situations.The description also says it reads "frequency voltage"... I have no idea what that means, but I doubt this probe does anything with frequency.Overall, I am happy with this tester so far. It didn't take long to modify it to my liking, and it feels like it'll last for a good amount of time. I don't use these testers every day, so your mileage may vary. I don't think it'd hold up in a severe duty environment, but for a home gamer or light shop work, it is fine.
