That makes sense.
I think that made the Dynohub illegal in most of Europe, where the law required a lighting output of 3 watts - 2.4W for the headlight and 0.6W for the taillight. Plus, with 1.8W and old-style bulbs, you'd be hard pressed to see enough at randonneuring speeds at night... -- Jan Heine Editor Bicycle Quarterly 140 Lakeside Ave #C Seattle WA 98122 http://www.bikequarterly.com
