One thing about super bright lights.... If you will be doing a lot of riding where it is truly dark, then you may want one like that. If its pretty well lit and you need it for the dark parts in between or to be seen with, then super bright lights can be a bit obnoxious... you really blind people with them, especially if you are bike path rider - be sure to aim them very well. If they are on your bars, point them at the ground. If you have your light helmet mounted, be sure to look away from other riders. By all means, use a helmet light to alert drivers, but don't blind them either. A quick flash should be all it takes.
