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.

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.

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!

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.

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.

Works like it should. Displays a little bit hard and the bright bright daylight but you can still see it. It is lighter weight than most of the non-digital testers but it looks like it should last

Red light and volt meter works but have yet to see the negative green light work. ** Update: Vendor quickly issued refund because negative green light didn’t work. Increasing rating from 3 to 5 stars for good service.
