If it is so, there's no need for the following: one extra feature of some bicycle's lamps is to load power into a condensator(?) (or what ever it is). If the electricity from the dynamo is missing during stops, the thing is unloading, keeping the lamp burn for a while. Maybe not a interesting detail at all, Knut
