It sounds like a light that would be best suited for a kids bike who isn't going to really be riding at night but wants to be more like their parents. I have sold similar lights marketed directly for kids and also gotten some in give away situations like branded corporate stuff. Would not want to trust it for actually keeping me seen especially not in inclement weather. 2 lumens is not much and 2 lumens in even less visible conditions seems even worse.

I understand that these lights are generally low initial cost and small and unobtrusive and all of that but I want to be seen easily without struggle and am willing to spend a tiny bit more to get that.
