I think it's particularly useful on bike paths which in our area are often shady and makes my approach visible from quite a distance. The "Senso" feature means that in the "T" setting the full beam will come on when it gets dark enough. If you go through a tunnel for instance, the full night time beam illuminates automatically. It comes with full wiring for itself and a tail light if you want one.
I have this one too, for several years now. I love it.
