It's way cheaper to build your own. You can also make it so that you can have extra relay spots for additional accessories. 12 gauge is more than plenty for headlight wiring. If you are going with LED. You shouldn't even need to upgrade the wire very low current draw. I also have mine connected to waterproof connectors and built a set of h4 to waterproof connectors so if my LEDs go out I can swap a set of halogens in on the trail
