It would be great to see bicycle lighting systems so that there's only one battery (rechargeable, lithium) and one button to press every time you turn on/off your lights. The button and battery would control the front lights, rear lights, and an additional light you may want on the sides. It would make dealing with lights quicker before and after the ride, it would make it easier to manage the batteries, and you'd never forget to turn of those rear blinkies!

Anyone know of such a system?
