Well NeezyDeezy, you were right about the size. I was able to fit it into the Optronic housing by drilling a small hole through the small overlap between the front and back of the housing. The LED light does not throw as strong a beam as the halogen, but works great as a to-be-seen light. I think I can now experiment with smaller/lighter batteries.
Also, you can see how I mount the light by using a Minoura Bottle Cage Holder, and sawing off the 'wings' that the water bottle screws into.
