.........I also agree with getting a light of some sort up higher into the line of sight of the car behind you. I believe that a third brake light could be nicely mounted between the two roll bar hoops. A modulator on this would also be my choice.
I think you have just described the Australian M3W's high level rear stop light Dan. Part #U340032, mounted on pedestal #T400037.
The common to all models 2014 on wiring loom includes a socket dedicated to feed this light.
