It's a 3w single LED StVZO light from Germany. It uses 4ea alkaline
or NiMH AA cells. The StVZO beam pattern is somewhat rectangular, and
in my opinion looks quite good. I've only gone for one short ride so
far and it worked quite well.

Just one problem.... I have no idea where you can actually buy one in
the USA. There's the name "Star" and a number "K1009" on the top. The
bottom has some other info stamped into the plastic that will require
a microscope to read. I'll photo that tomorrow when I get to my
office.
