Review on 🔌 7865L 7-Pin Trailer Circuit Tester by Dewey Galyon

Great tool I use it all the time. The tool allows you to quickly determine if there is a problem with the truck or trailer electrical lighting system. Compared to my peers' Snap-On version, the only obvious difference was the presence of the Snap-On logo and a markedly different price. Many truck drivers and other mechanics have told me that they have never seen such a tool. Most of them say they will get it now. Have been using it for a few months now and use it almost every day as long as it lasts. still looks like new with no functional issues.
