Can anyone recommend me a bike light that is rechargeable? I would prefer something USB based for compatibility reasons. I have a decent bike light now. The problem is that it runs on AAA batteries which would be fine, but the optimal light output is 50% charge and above. I don't want to have a pile of half charged AAA batteries when the only other devices I can use them in is remotes and my grill starter. I don't want to "get my moneys worth" by using all the battery. I should say I'm only out after dusk a couple of times per month, but when I am I want full bright light for safety reasons.
I've been looking at the Light and Motion Urban line such as this one.
