I've been riding with the Luxos U on my new commuter/tourer for about a month and have been happy with the performance and convenience in comparison to my previous re-chargeable setup. I do have a B&M Toplight Line Brake Plus wired on the rear as well. Depending upon the riding conditions, I will supplement these lights with a helmet-mount light (flash mode) and a Light & Motion VIS 180 (pulse mode) on the seat post. Overall, I really like the dynamo lights, especially the optics. While not as "blindingly" bright as the Dinotte Lighting set this has replaced, I feel the beam pattern of the Luxos U is more useful, and more "appropriate" for road riding.
