Could you add an example of a situation where you would see an indicator light on the bottom of the bike but you wouldn't see a whole arm?

How often do you see cyclists even raising an arm.

Also most cyclists I see love wearing dark clothing, especially in winter, at night, without any form of adequate lighting!

Well in my experience as a cyclist, I'm sure you see a lot of them as most drivers are focused on their phones, their radios, the scenery -- anything but the road.

Please can we avoid subjective generalisations like this.

I think it is the case that an amber pulsating light would grab the attention of drivers to the fact that a cyclist is hand signalling & turning.

At dawn/night for example.
