If I recall, that's the one GB has, I contacted them and think said they don't do it on ebuy anymore, just through their w-site...sounds like much the same as the `GAMMATRONIX`...as I have a volt meter on board anyway, I mainly need something to remind me that the light is on when I park up (even in the dark), and actually while I'm riding too- as it seems the headwind pushes the light back into the darkness of the reflector
