At this time of year my bike is fitted with a hub dynamo. The switch in the lamp is broken. So it’s always on.
At the station I need to guard it, so not to signal to, or annoy the drivers.
It’s important to keep a good light,
But also to shield it,
For it can surely do harm,
As well as good.
Never thought of this before.

I could use a bike with a dynamo this morning! So wet and dark.

Try not to! Although it’s not beyond the bounds of possibility.
