Without a doubt the new led lights are awesome, however the battery packs are too small, at least on the ones I've seen, to go for much distance. But the good batteries, that are available, are small enough that they can be hidden or made fairly incognito, in a usable pack for a longer distance. There's lots of room under a Tomos seat to bunch them up or a small box/pack within the rack or between the fork tubes. Lots of room for creativity.
