2. It causes oncoming motorists to see the cyclist much earlier and, for
example, if a big semi comes they can pull a bit to the right so the
semi can give the cyclist wide berth.

I do NOT believe any practical light allows a motorist to see a cyclist
_much_ earlier. In almost every case, I've seen on-road cyclists before
I noticed that they had a light. And in no case did I see the light
early enough to make any practical difference. You're fixating on a
superstitious talisman, imagining benefits that don't exist in real life.


I think I've mentioned seeing the bloke on a bike wearing bright
orange knee socks nearly a kilometer away :-) I remember the orange
socks but can't remember whether he had a light on his bike or not :-)


I wonder what the reaction would be if said bloke participated in a
business meeting wearing bright orange knee socks.

The subject was bicycle visibility, not business meetings....


To me a bicycle is not just a piece of sports equipment but foremost a
transport vehicle.


... but
having said that I might comment that it is not difficult to change
socks, even sitting on the roadside curb.


And change all the other things sitting on a curb in a business park? I
rather flick a little switch and have instant visibility. Upon arrival I
flick it again, visibility turns off. Simple.

As I said, I noticed the orange socks going up and down a kilometer
away on a bright summer day. I doubt strongly whether your super-duper
light would even be visible (in bright daylight) at that distance.
