Hmm, I wonder if the High/Low beam switch on the 08/09 could be modified to act like the F2P on the 10/11 (Low beam press hard is momentary F2P). Then the display mode selector could be added to the finger trigger, without loosing the Flash feature.
The assembly isn't broken down in the parts diagrams, and it's probably not worth $100 to anyone to add the newer style housing. It would be interesting to know if anyone has looked at that option when they had their handle bar controls apart.
