I wanted to add exterior LED lights to the trailer to light my kitchen and surrounding campsite. Initially I was going to mount spots on the exterior at different points of the trailer, instead, I went with a more flexible approach. I purchased three lightbars, a dimmer switch, and all the wiring to plug into my 12 volt plug (in my panel)
It turned out really great! I spent less than $80, and each light bar has a magnetic back and i can move them around the trailer depending on where I want the light. When i pack up, they stow away so i dont worry about theft or damaging them on the trail. Maybe not ideal for everyone, but this solution works perfectly for me...
