I received my Gemini "Duo" http://gemini-lights.com/products/duo headlight yesterday. Took all of a minute to hang on the V20. Charged up the battery pack and...wow! Very bright light with a remote control switch that works perfectly. I have initially mounted this on the chainstay cross-member...but will remove it to the fin when the mount for that arrives. I went for the 2-cell battery, I'll probably not need more than an hour of 'solid' light on any given ride...the rest will be blinky, using less power, etc. When I get the DS-500 rear light re-mounted, I'll be done with lighting!
