Hi Jeff, I have not completed the Harley high intensity LED project yet. I'd sure like to exchange emails with you offline from PIClistserv. Your project seems light years ahead (no pun intended :-) than mine. I would like to build one similiar for this guy as he uses it as a family/weekend cruiser like so many others. What about the severe vibration, is the accelerometer portion immune to this?
