My first proper bicycle in about 1972 had a hub dynamo (should have been called an alternator, that what it was) along with a battery tube for 3 D cells. On top of that was a bridge rectifier and a single diode to prevent back charging of the battery. And yes, it was to provide light when stopped, the law was changed (in the UK) quite a while later. BTW the rectifier and diode where selenium.

I think the item is a splendid thing.
