Amazon Customer: I like that you can see the Pulse Wave in the BK signal. The led lamps are kind of small so I used my drop lamp to see.

Mancel Fox: I wasn't sure how to figure out the wiring & if it was working. It told exactly what was right or wrong.

David: Works as described. Lights are not that bright so it's a bit annoying when working with it outside in a sunny day. But it works great.

Glampur: Bought this tester to be able to test and troubleshoot my RV 7way wiring to my toad. It works well and is easy to use. It makes the troubleshooting go so much faster and is a quick way to test the wiring before you hook up and drive away.. Small enough to fit into my overloaded toolbox, and is a great tool for the purpose.

Mr. D: I bought it to test the tow light of my VW because my car’s warranty is almost over. I connected it, only one light is blinking with high frequency. So I brought my car to the dealer. The dealer told me I have a after market tow light connector, so I have to buy a original. I spent almost $100 for a connector. It was still not working with my tester. So I ask them to do more test. They checked and told me it should be fine, but they don’t have a tow light to test. Then they bought a portable tow light to test, everything works fine the portable tow light. I have to pay another $100 for the examination because they spent about a hour on my car. That is the story how I lost $200 because this tester. I returned this tester after all this. It could be I happened to bought a faulty tester, but if I want to test the tow I will buy a portable tow light.

While it isn't hard, it's cumbersome and takes a while setting up. With this tool, it makes it 99% easier to grab and plug in and a quick check. Had a customer that came in saying the left side signal on the trailer was working but the right side didn't work. The customer plugged the trailer into a different vehicle and worked correctly. Connected this tool and found the brake lights and left signal worked but the right side didn't. Found a blown fuse and corrosion inside the socket.

There was many of these to chose from, but this looking like the most basic and easy to read is why i picked it. There is 6 LED's (RT signal, LT signal, TM, 12V, BK, and BU). This tool doesn't allow you to load test the circuits just a visual of if there is power or not. Another thing i do wish was there was a swivel head so i can see it from the top, the...
