This Brand New Beep Adapter With Built-in Circuit Tester from Bully™ converts a 7-Way RV Blade to a 6 Pin Round connector and allows you to test each of your trailer functions from inside your vehicle.

This award winning Beep Adapter With Built-in Circuit Tester from Bully™ is perfect for today's electronic lifestyle. For the first time an individual person towing can easily test their lights, BRAKE lights and all electrical functions on their trailer while sitting inside of the tow vehicle.

Simply click on the built-in "test" switch indicating "trailer" then test each trailer function individually, listening for each function to beep indicating a good working circuit.

Should you discover a problem on your trailer by not hearing a beep on one of its functions, you can flip the "test" switch to check your vehicle's connections isolating exactly where your problem exists.
