How to Power Interior Lights of an Enclosed Trailer


I have an enclosed trailer with interior lights. These lights are powered when plugged into a vehicle. There are times when I need the interior lights to work and I don't have a vehicle to plug the 7 way trailer plug into. Is there a way and what would l need to just run the interior lights on a stand alone generator? I would like to wire an extension cord to a connector with a female adapter for the trailer.

The best way for you to power the interior lights of your enclosed trailer is with a mounted 12V battery. To do this, mount the battery with a battery box like # TLA7708R and use a junction box # 38656 to tap into your 7-way. You will also need ring terminals # 44-5310A, and wire # 12-1-1 to run to each light. You will also want a light switch such as the Pollak rocker switch # PK34308 or toggle switch # PK34571. You will be able to charge the battery when the 7-way is attached to your tow vehicle, but if you plan on being unhooked for an extended period of time you will want to think about using a battery charger, the CTEK # CTEK56158.

If you wanted to use a generator you could, but you would need a generator with a DC outlet such as # BTGEN7500DF and then wire all of your lights into a DC plug, a process that would be costlier and more difficult than using your 7-way with a trailer-mounted 12V battery.
