Hi there,
Here's my contribution to the DIY Bike Light list.
I think most of us has seen the Ultrafire WF-502 flashlights:

Take a lathe to shorten the body tube, re-thread it and fit a "generic" CREE drop in:

Here's what you end up with:

Fit it to a Bike clamp:


Obviously for a bike I'll need 2 of these:

Get an extra WF-502 and make a new head:

Finally make a "Y" cable to connect to both lights. I can use either a 1x18650 body for a lightweight 1.5 hours run time of use a longer 2x18650 body for 3 hours run time.

Thanks for looking,
Bogus.
