Automotive Test Light with 3-48V LED Digital Voltage Display, Auto Circuit Tester with Voltmeter & Dual Color Polarity Indicate, Electric Test Pen w/Stainless Probe for Car/Truck/SUV Checker

Very reasonably priced and works great. Not only a test light, but I actually displays digitally what the exact voltage is.

Amazing little test light. Feels like a quality tool. Works. I wish I had this 40 years ago.

Excellent product for a good price! Works perfectly!

Probe is extra sharp to pierce insulation on wires. Digital read out is Excellent..! It show voltage polarity, and voltage count. It comes with a cover so you don't injure yourself. Nice quality and great idea. I would highly recommend this unit for mechanics or electronic technicians.

Works as intended, and displays the voltage. Alligator clips attachment is a good touch. I do wish though, that there was a diffuser on the light indication as one has to be looking square on at the device's voltage display to see an indication of voltage. If the device were held 180 degrees off, I wouldn't be able to see anything. This is a non issue however and only requires the user (me) to adjust the viewing angle/how I hold it so I say it's a non-issue.

This tool is an excellent value. I was pleased to see that the quality was excellent. The handle is crystal clear, tough tool grade plastic, such as we are used to seeing in expensive screwdrivers. It has a positive grip in your hand and is easy to use. The voltage display is bright, and the readings are accurate. This is a top choice, and I recommend it.

Works as it should.

The tester works on minimum voltage of 3VDC to register a digital reading. I have tested 12VDC system with a fair accuracy. Tracing wires is fairly good as long as you have a common ground.The digital readout is helpful if there is a voltage drop in the circuit.
