Innovative Products of America Light Ranger MUTT®: USA Made Universal Portable and Water-Resistant Trailer Light Tester with 7-Way Spade Pin Style with Adapter (D20C Battery Adapter)

The #9101-D20C Light Ranger MUTT with Integrated Power-Management Technology is a portable, water-resistant trailer tester with a built-in, proprietary, smart adapter system compatible with DeWalt 20V power tool batteries. It makes trailer testing more flexible and reliable in the field by simulating all trailer circuitry without the truck. The standard 7-way spade (J2863) connector and included 3-way trailer adapter allow testing of 7-way flat, 6-way round, 5-pin and 4-pin trailer connectors, making it a versatile solution for safety checks, troubleshooting and routine trailer inspections. The patent-pending adapter acts as a precision-regulated power plant, stabilizing current while providing a failsafe barrier that protects the trailer, circuitry and battery cells from short circuits and premature depletion. By maximizing efficiency, it significantly extends runtime, allowing more tests per charge while neutralizing RF interference and heat to ensure 100% diagnostic accuracy. Built for light-duty trailers, it simulates the functions of a standard tow vehicle, allowing fast, fuse-free testing for RVs, boat trailers, landscape rigs and more without needing a truck. With built-in short circuit and battery protection, rugged construction and USA-made quality, it’s a must-have for technicians and trailer owners.
