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

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.

You can’t go wrong with a multimeter, but a proper test light can be a quick and convenient tool for checking and diagnosing automotive circuits. This ATOBLIN Buzzer Test Light is a significant improvement over older versions that simply illuminate a bulb to indicate voltage. Having a clear digital LED display is useful for identifying normal/high/low voltage conditions within the 4v to 60v DC range of this tester. The alligator clip is large enough to easily grip battery terminals and the 102” coiled extendable cable make it easy to reach across an engine bay if necessary. The pointed tip is perfect for testing installed fuses and the tip cover is conveniently integrated into the cable. I do not recommend using the tip to pierce insulated wires. The red/green polarity indicator is a nice feature, and the audible buzzer serves as a secondary voltage confirmation for occasions when the display might be out of view. It is not advisable to use test lights for diagnosing computer-related circuits, but for general purposes this works great!

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.

This test light pen is exactly what you will need when locating problems or troubleshooting a little electrical. The pen is simple but efficient with bright lights and a strong buzzer and the clear casing is so awesome and easy to read. The pen is of a hard material that seems will last but only time will tell how long and the price of the tester is fair thus will be a perfect addition to the automotive electrical arsenal.
