Complete portable kit. It has all the wiring, the 4-wire connector plug, and two-sided lights with magnetic bases. They are red on one side and amber on the other. Plug it in your vehicle's harness and stick the lights on. I bought the kit to use on my 5x8 tilt trailer, just to stick them on it when I was pulling it on the road, but obviously I never opened the package, instead I sold the trailer. $15 shipped to the lower 48. Other places higher.
