Well I've finally sorted out all the issues with the cicuit, and have been using my light for a couple of weeks now. Unfortunately, at this time of year I only ride home in the dark once a week, so I,ve only actually needed to use it twice.

Still, it's pretty nice. It gives a nice bright light where I want it, and gives some light up to 90° either side, so there's no sudden drop off of light at the edge of the beam.

In flashing mode it's visible in daylight. I've been using it during dusk on my evening commute and have noticed a lot more motorists heads turning my way.

It's only got a couple of hours run time in the batteries so far, so I don't have any concerete figures on battery life yet.

See the new webpage I made devoted to it here

ps. I very very happy to see bikeforums back on line. I missed you guys.
