Recommend me rechargeable lights

my evening commutes are getting darker and darker. my antique nimh powered vistalite 10w/15w is near the end. i want a bar mount that is super quick release with no residual mounting ware and with a bottle cage battery.

Insofar as the products mentioned are probably for the most part available in the US, have a look at this thread from bikeradar:

Though if you've been using 10 and 15 watt lights you presumably want something pretty hardcore right?

you WANT a bottle cage battery or you dont?

i'm selling a knog gator light, you want it?

It doesn't sound like what you're wanting, but I currently use the Cateye EL530 and LD1100 and find them to be excellent. They're very very bright indeed, with lots of versatile flashing modes on the rear and seem to have a good life-span on rechargeable AA batteries. I'm going to add another (different) set of lights this winter though, as Glasgow traffic seems to be totally blind to cyclists, even with these guys blazing away.
