Still not seeing what you like..
This the Optronics Qh-7CC setup on my other bike..using the front fork reflector bracket..
If you still want more geekiness.. Here is one setup using a Dorcy 4AA flashlight.
Using Cateye spacer 533-8730.. I screwed the spacer on my front Blackburn rack (flat surface). I used the same handlebar mount clamping to a PVC pipe.
Repeating the process, I screwed the 533-8730 onto the flat side of the Dorcy 4AA light and then using the handlebar mount on the PVC pipe..
The Dorcy 4AA can accomodate a MR16 lamp.. and I install a MR16 lamp holder in the flashlight and a surface mount 5.5mm x 2.5mm jack on the back end..
Since the light is translucent yellow.. it has great side visibility.. Great setup for a 10W MR16 lamp.
