Except that when the tyre sidewall is slippery or when stopped at traffic
lights etc, it's nice when your lights still work!

Even with a small secondary cell to cover brief interruptions from the
dynamo, I prefer to keep my cycling as effortless as possible.  So I
recharge my lights from the mains supply at home (or from a solar cell etc)
intead of powering them as I ride.

A good bicycle headlight is at least 10W (ignoring the little candle-like
ones!), that might be an extra 50-100W of dynamo effort, which is quite a
lot for me!
