Obviously not simple enough.
If a person is sighted and able to see then they have a responsibility to use that vision to cycle safely and to ensure that with the aid of adequate lights to either see the road ahead, or to travel at a speed where they can.
For someone who is partially sighted then there are issues, but not in this context. If you are going to argue that speed hupps should be removed because they are a hazard to those with poor sight, then you will also need to remove:
Kerbs
Streetsigns
Trees
Illegally parked cars
Buildings
Houses
Shops
The law is about visibility - not seeing.
Not only suggesting it but actually doing it!
.. and I am not the only one. Most experienced cyclists on a mixed commute will have lighting systems that can offer high power when required or lower power when not. It enables us to see the road ahead of us
The CREE T6 offers 3 different levels of brightness, there is no need to use another light if in possession of one of these in either lit or unlit area's....only as a fail safe backup. If anything, the lower powered light should be better used in unlit areas as your eyes adjust to the lower light levels...the reality is though that our eyes function better with higher light levels, and so the lamps sold should conform to a minimum standard which is much higher than the current 4 lumens
The fact that you are using a CREE lamp yourself is testament than you don't consider the minimum standard to provide adequate performance....Next!
@Smeggers II has just agreed with me in his edit
