VenmoHello I recently started building and selling trailer light test boxes. I also make a version with air hookups for testing trailer air brakes.
The boxes will test both heavy-duty semi 7-pin round connectors and 7-pin flat RV-style plugs. They run off a cordless tool battery, and I can build them to work with the battery platform of your choice. I have sold many of these and every one really likes them a lot.

All boxes include a 3-foot trailer cable lead. An 8-foot cable lead is available for an additional $30 per box. All air brake testing boxes include a 12-foot set of air lines.
