Those are Kuryakyn driving lights. I simply spliced into the wires coming from the ACC switch on the right side. Nothing else was hooked to that switch. It was easier to tap into the wires at the switch rather than hooking into the plug under the seat.

 

I had my 550 mounted that way on my 07 for over 2 years. I helped a coule other guys with the same install on their bikes. They're all still very happy with the look and the location. Only negative would be looking down at it. Not an issue for me though. As you can see from my pics, it is just below the speedo and tach.
