Description

For the first time an individual person towing can easily test their lights, brake lights and all electrical functions on their trailer with a beep to indicate 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 the connections in your vehicle isolating exactly where your problem exists. This is the multiple award winning product of Bully.
