Review on πŸ”Œ RV Trailer Plug Light Circuit Tester Adapter - 7 Way Blade & 4 Pin Trailer Wiring Tester for Boat SUV Truck by Michael Wilson

Revainrating 5 out of 5

Just what I needed in chain testers

I bought a truck with a lot of problems and was slowly fixing it. I wanted to travel for a trailer and a Harley. Wasn't sure if the trailer lights were working or not saw how the wiring harness was spliced under the bumper. Wanted to check it out before I went and found out I won't be having trailer lights, this thing didn't disappoint. If I ever lose mine I will definitely buy them again

Pros
  • Quality construction
Cons
  • Hard to tell
