A little late, but on the topic of stuff being stolen off of bikes:

The argument that if everyone had lights, people wouldn't steal them, is bogus. People steal saddles and posts all the time. I always take my headlight and tail light with me when I lock up. The first time my gf parked her bike outside, someone stole her junky Blackburn pump. I do not believe for a second that people won't steal whatever isn't bolted down, which adds weight and decreases convenience. I hope the US never requires dynamo lights; the ones I use, with my reflective tape, are more than sufficient to be seen, and dynamos would only add weight and suck power from my ride. No fun.

Maybe it is the EU's laws that need to be updated. As we've said, battery-operated lights have come a long way in the past few decades.
