I have the 2010 Buell OEM LED taillight (part #Y0401.7AC) and love it. Way better than stock and only $47 from Surdyke.com. They make 2 versions of the taillight....one with a license plate light and one without. I have the version without the license plate light as I still have the stock tail on my XB9SX. If you do a tail chop you probably would want the version with the license plate light (not sure of that part number).
