Yes, it's a bike light, however… the lens and reflector combination mean that you don't need to burn the possums in trees and retinas of fellow commuters coming towards you just to see the ground. Instead the beam is formed such that there's a distinct horizontal cut-off.
Automatic mode is a bit shonky and I find low output fine for riding on paths and on-road lanes.
Sound your bell before passing. Be kind to one another on the paths.
Edit: There also seems to be a slightly heftier SFL-04 model on preorder for USD $7.99 / AUD $10.71

Use the $ sign before the numbers and see the magic !
