I have 3 sets:

Niterider MiNewt Dual x2, NiteRider TriNewt, PrincetonTec Switchback 2

I normally run the MiNewts on my bars and TriNewt on my helmet. If you run that setup indoors, nobody else will needs light though...

Anyone is welcome to use them...as long as they make it back. I'll make sure they get fully charged this weekend.
