Review: Would highly reccommend this for checking trailer light issues - Just what we needed. Got the replacement wiring harness for a trailer and still had issues with the lights. This saved a lot of second guessing and found the problem - which was the last thing suspected. So instead of going thru all the wires and connections, this found the problem quick! Wasn't even thinking of one of these when we bought the harness. Glad we got it! Worth every penny - saved a lot of time and frustration.

### ⭐⭐⭐⭐⭐ Great but easy to losel
*by C***L on September 9, 2020*

This tester works great. I keep in the glove box in my car. Recently I had my car in the shop so I took it out of the glove box with some other stuff I didn't want to go missing. Later I couldn't find it. It had fallen on the carpet between the console and the passenger seat which here all black. I drilled a small hole in it and put a small piece of neon green cord through it. Now it is easy to spot. Hope this idea will help someone avoid losing one. .
