Also, I went to a product design exhibition in Berlin this summer, and there was a bike which had LEDs set into the handlebars and seat tube. It looked pretty good, though the obvious concerns would be bartape and what happens if the circuitry fucks up. You'll need to dismantle your bike for a couple of lights.
Look very similar to the Aura Lighting System.
