Hey, I would like to put 2 yellow running lights on each side of my truck box. I have 2 options that i am considering. A: Mount them on the side, and put them all out to a 4 Pin trailer receiver, run it under my truck, and then plug it in at the 4 pin. or B: Mount them and run the wire into the electrical system and place a switch inside my cab to be able to turn them on and off from inside. I would like to do A because it would be easier, but i want to do B because it would be nicer and i could use it while pulling 4 Pin trailers. If i went with B, how would i do it? I know nothing about electrical and lighting systems..... Thanks!
