I mounted a light on to a friend's bike fork since she has a basket. The option that I went with was a Serfas SL-30WP light with a Serfas Universal Headlight Bracket. This was a pretty good set up. The bracket has lots of room for adjusting the angle of the light and if she decides she wants a brighter light in the future, she can just throw on another light.
