ATOBLIN Buzzer Test Light Automotive, 4-60V DC LED Digital Circuit Tester, Heavy Duty Light Tester with Voltmeter, Auto Voltage Tester Electric Probe Test Pen for Fuse, Battery, Polarity

This circuit tester worked very well for setting the timing on a old air cooled VW Beetle engine. The photo does not show it lit up but it displays the voltage and makes a sound when the circuit is live. The rubber cap to protect the tip is part of the cable so it will never be misplaced. Works very well.

At one point or another weve all had to check a fuse or circuitry with a test light. Owning a home or motorhome/RV a test light is guaranteed to be needed at some point in time and especially in a motorhome. Its easy... just clip on the flying lead to a ground and then touch the pointy end to your fuse or fuse port and you get either get illumination or not. Theres the kicker... the light that may come on can be varied in brightness meaning voltage is present but, just how much? It may not be enough to just see test light come on, you need to know how much to correctly diagnose a potential issue. Thats where this bad boy comes into play with its digital voltage display and sound indicator. You can attach it either to negative or positive ground, there is also a light emitting diode on the circuit board for polarity indication, red light indicates positive polarity and green light indicates negative polarity. Once I used this test light and receiving instant feedback; it gave me an understanding of what I was potentially dealing with for a quick solution. To me, this ATOBLIN Buzzer Test Light was akin to bringing a gun to a knife fight. Its that advantageous.

Helped me narrow down where in one of my circuits wasnt receiving any power. So it helped me save time.

There’s nothing more annoying than trying to figure out a faulty fuse in my car. This is a pretty good tester, easy to use and reliable. Metal clamp on one side and the pen on the other. The reading lights up and beeps. Good tool to have around for me.

This is an easy to use tool that makes testing voltage both simple and convenient. You get a both a digital and audible tone. Photos show it attached to a 9V and car battery. You can see from the close up photo that the end of the probe is nice and pointed for accuracy.

Although this is relatively simple device, it shows that you do not need a $100 analyzer to do simple checks on your automotive wiring. Continuity checks, fuses, lamps, etc. can all be done using this simple device as powered by your own vehicle battery. It has audible signaling as well as a digital voltmeter display. I think that even for something as simple as checking fuses, this device needs to be in your automotive tool box and/or your vehicle emergency kit. High recommended!

This test light shows a digital readout of voltage and features a buzzard for alerting mechanics. The voltage reading is 4-60V DC LED reading. can perform bidirectional testing of negative and positive circuits nice tool for the home mechanic and tradesmen to have with other diagnostic electrical tools in the toolbox.

For the price you cant not have this tool around. Mine doesnt buzz but has light that comes on when testing. Not sure if its supposed to make noise based on pic or not but mine doesnt, works well though.

This is great in a pinch for automotive work, you get a quick voltage read out, and it works well.

Bright, easy to read digits for voltage. Super sharp probe allows for testing the wire without having to strip. Loud buzzer to detect voltage and strong ground clamp. Rubber probe cover an excellent addition.
