Trailer lights electrical question

Thanks in advance for any and all ideas shared.

I pull my layout boat trailer with my Polaris Ranger on a paved county road approximately 2 miles from my house to my marsh. I would like to get the running lights to work for safety purposes.(I'm not concerned about brake light or turn signals) for this short pull. I am think of putting my extra deep cycle battery in the bed of the ranger, design an adapter with battery terminal clips on one end and a four way plug on the other end. Thinking I would be able to just use the ground of the four way with the negative clip and the running lights with the positive terminal and not use the other two wires from the four way plug? Would this work or not to give me running lights on my trailer?

I am hoping this would give me running lights when I use the Ranger and still be able to pull the trailer with my truck when we travel to other places and thus be able to use the existing lights/wiring on the boat trailer without any modifications to it.

Thoughts??
 
Should work just fine povided the lights on the trailer are also grounded to the "ground " wire on the trailer side of the plug.
 
Does your Ranger have a 12V power outlet? Can you run a wire from that to the trailer lights? Or how about a couple of bicylist red lights powered by a battery. Moount a couple of those on the back and turn on as needed.
