I was too afraid to cut holes in my lovely new (to me) VFR800, so I decided to go 'old school' and fit an LED voltmeter to the mounting bracket for my heated grips. The end result may look a bit 'Radio Shack', but I think that the two units match each other very well and that the LEDs don't really look out of place next to the heated grip control. YMMV  , of course.       Thanks a lot Photobucket  !
