The Wesbar electrical circuit tester is the simplest way to check the continuity of the lighting circuit on your vehicle when you have a 4-Flat connector. Plug it in; indicator will show if the circuit is functioning. The attached molded tethered with loop allows for installation as a cover to protect the 4-flat connector while at the same time testing the circuit when not towing a trailer.
