A Croft Trailer Supply Original! We designed this test box as an aid for testing trailer lights and electric brakes. It allows one person to visually test brake lights, tail lights, right and left turn signal lights and electric brakes by simply connecting the test box to the front of the trailer and taking the hand held control unit to the rear of the trailer to test and make repairs as needed. This eliminates the need for two people to test, and or one person going back and forth between the vehicle and the trailer. Three different connectors are included.
