In this age of tech, surely there must be rechargeable lights that can

Two word.

Stand light.

This is short term storage in the lights (capacitor I assume) which
means that they stay on for a few minutes after you have stopped
pedalling.


When a lad I tried wiring the dynamo to a bridge rectifier, battery and
then the lights, but the charging load made cycling hard work.

With modern day charge controllers and very light (LED) loads, I'm
guessing it would be far more doable.

When I were a lad my bicycle had a front dynamo.
One Christmas present as an add on was a battery tube (I think it took 3
cells) to use when stopped at the lights.
The front light had a 3 way switch under it, on, off, battery.

Tell that to the kids of today etc. :-)
