The Scout is an affordable, portable trailer wire testing solution designed for anyone who tows a trailer and demands accuracy, convenience, and durability. This all-in-one diagnostic tool allows you to test any standard 4-pin trailer connection without needing a tow vehicle — saving time, effort, and guesswork.

Powered by your DeWalt or Milwaukee 20V or 18V tool battery, the unit delivers reliable circuit testing for turn signals, marker lights, electric brakes, and more. The integrated 4-button wireless remote puts full control in your hands, allowing you to walk around the trailer while activating each function independently for quick visual inspection.

Built inside a rugged, impact-resistant enclosure, the test box is engineered for home, roadside, and field use. Its intuitive layout makes operation simple and efficient, even for first-time users.
