Found one of these in a box at the local Performance tent sale earlier today for $99. Figured, what the heck, and grabbed it (only one). Just hooked the battery up and ran through the different light setting and I am pretty impressed. Looks like it should be good for the urban street and dark MUP riding I typically do.

Doing some quick searches, I get the idea/impression that there are some simple ways to upgrade these lights for better run time, charging time, brightness etc. Battery space seems to have pretty decent battery packs. Any suggestions?
