ATOBLIN Test Light Automotive, 3-60V DC LED Digital Circuit Tester, Heavy Duty Light Tester with Voltmeter, Auto Voltage Tester Electric Probe Test Pen for Fuse, Battery, Polarity

Works great

This is a must have for all 12v techs. I am a 20+ 12v tech manager at a large shop and have owned many test lights Over the years. I ordered this test light to replace my broken snap on test light while the parts to fix it arrived. I am amazed at the quality and functionality of this product. Very well made and the built in voltage meter is very useful. Makes troubleshooting much faster. I will replace that $50 snap on test light with this less expensive and more modern one. I will use the snap on as a backup.

great tool for when you need it. does what it is designed to do

Wish I had it sooner! This was surprisingly useful. Connects to either ground or positive circuit posts and indicates which you are testing, along with voltage present. Look forward to using it for tracing trailer wiring circuits.

Love the product fixed all my electrical problems on my boat

This is a very good product for any auto mechanic or at home DIYer auto or electrician. When connected to a ground source, it indicates when you probe a positive power source and gives you the voltage read out or when connected to a positive source, you have the opportunity to probe negative ground wires and has led lights that light up accordingly. Very pleased with this would recommend to anyone

high quolity i like it and recomend it

The tester is much better than I used to see - high-quality casing and insulation, bright and easy-to-read display. Voltage measurement is a much-needed function - it saves tons of time when foaming around vehicle wiring and lets you do most of the tasks without ever needing a multimeter. Definitely worth the money and much-needed convenience upgrade for a typical multimeter operation. Cannot recommend it highly enough!

Nice to have a test light with a volt meter and polarity

Nice DC voltage tester. It comes with just under a 9-foot cord. You can connect one end to the power source and the other completes the circuit. You can also check to see the voltage being carried. There is a bright LED that displays the voltage and you have a range from 3 to 60 volts all direct current. This will also tell you polarity which is positive and which is negative. Great tool for figuring out voltage at a reasonable price.
