Well I have managed to rig up x3 heath robinson options:
1) Using the origional clip (too small) I can place the light on the far right of my bars and fix it in place with my hair bands (i have a big pony tail)! Works ok for short no bumpy stuff....to the pub etc
2) PLace sticky back velcro pads on the back of the light and the front of the bar bag and simply stick th elight on there....works because this is a very light weight light.
3) My bag (carradice overlander) has shoulder strap ring attachments on each side. I can tie a spare pedal tie clip between the two across the front of the bag and tie the light onto it again with my multi purpose (pat pend
) hair bands!
Nothing ideal...but all will work for now on a summer tour where it is likely i wont be doing much night riding anyway.
