Good work splats - she's still working well. Next version you might want to try shorter wires, or ones that can unplug so it can be routed through helmet zip ties or whatnot. But I bet you are way ahead of me and have already thought of that.

Good bike light. I like it being light weight so it won't affect turning your head. Also it won't interfere with the effectiveness of the helmet if you hit your head. Where does the battery assembly go?

Where ever you want to put it , I personally carry in in my back jersey pocket so I can just reach back and turn it on and off easily
