OK, I need some help please. I have three bikes all with various kinds of lights/blinkies. I recently broke one light mount and need to replace it. So, I now want to standardize my lighting system to allow me to switch lights from one bike to another easily.

I want a 3 mode flashlight that is bright and provides me lights in darkness when needed and a daytime blinkie.

Where I need help is sorting all the various P7 parts and pieces out.

This is what I would like to order. Does this sound right to you people, given what I said I need the system to do?

Battery = http://www.dealextreme.com/details.dx/sku.5790 My question is do I need a single for the above light, or, do I need this two pack?

Thanks, your help is very much appreciated.
