I am in the process of stripping all OEM rear lights. I removed the entire lic plate OEM assembly and the main light fixture at the top.
The custom license plate bracket is now bolted into the depressed area where the OEM rear-main light fixture resides.

The wiring behind the OEM light fixture still provides the wiring for running and stop lights.
It tucks in nicely behind the license plate.
The remaining holes are taped over with "Trim Tape." When done with the mods, I'll have the fender tail smooth out and repainted to match...
The small rectangular running lights above the OEM license plate are now mounted above the new license plate location.

The signals are now coming from the saddlebag lights.
For brake lights I purchased two 9" led strips which can be placed virtually anywhere on the bike...
no screws, just 3M tape. I placed mine vertically,along the rear fender starting down from the bottom of the license plate.

(White, Blue, Amber, etc...).
I purchased them at one of the popular chain auto parts... not Pep Boys, not Kragen... err...
Senior Moment in progress! 
My $0.02.
