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?

Thanks!
