Innovative Products of America #9101 Light Ranger MUTT 7-Way Spade Pin Style with Adapter Trailer Tester

The Innovative Products of America Light Ranger MUTT 9101 is a great tool for testing trailer wiring without having the tow vehicle attached. The product accommodates all common plug types, and it is very easy to use. One of the main advantages of this tool is that it saves a lot of time, as it turns a two-man job into a one-man job. Additionally, it is rechargeable, making it a convenient option for people who work on trailers inside a shop. However, one customer reported that the circuitry went bad on one function after four uses. Some other buyers reported that the battery suggested on Amazon website is too big for this tool, making it impossible to close the unit. Overall, the Innovative Products of America Light Ranger MUTT 9101 is a convenient, efficient and user-friendly tool that represents a significant improvement over homemade testers.
