Paying attention to this thread. I've really been wanting to replace my symmetrical beam headlight with a shaped beam. My first choice right now is the Saferide using batteries (about $130 from a German vendor), or spending about twice as much on a dynamo system, but I haven't found a light where the reviews are as nice as with the Saferide. Of course, I haven't seen any of them in action, so for all I know I might be happy either way. I'm staying tuned for now.
