How are those tail lights working out for you? I'm looking for a solution similar to yours (battery powered) but also stylish like that. The only ones similar to what you have that I've found online are wired.
I got those rearlights from http://www.chopperdome.nl
They're not cheap compared to the wired ones, but the batteries last pretty long for buttoncells.
