Availability of 7-Way Tester for Trailer Without Tow Vehicle.

Question:
Hello! I am trying to find a product that will allow me to connect a female 7 pin trailer connector to the battery. My goal is to try and test my travel trailer running/clearance lights without the tow vehicle connected. Do you offer a product like that? Thanks

We have one tester available that will let you test your trailer lights without the tow vehicle. That is the Hopkins Tow Doctor Trailer End Test Unit # HM50928. This tester can be used with any 12V battery and will illuminate your trailer lights and test all functions.
I have attached a video review that shows how the tester works for your reference.
