Ow! My eyes! 
I charged up my shop light, and man it is BRIGHT!!!! Hurts-to-look-at-it bright!
Played around with it this morning when it was still dark, and I think considering how bright the 60 LEDs are when it is fully charged, I am best off putting it under the top tube. (like a frame mount pump) It is very light weight and not too wide so I think it'll be fine there. Besides, as I was getting it out of the package I accidentally pulled the water resistant gasket thingie off the rocker switch. (oops!) If I put the light under my top tube hopefully it will stay dryer.
I'll do a test ride tonight and ask SKnot if I'm visible.
