Here in London, some of the information boxes at bus stops have
a button that you can press in order to light them up, which
will allow a better view. But all busses have to be manually
flagged...

Only at those points which are a "Bus Stop (Request)", or on a
"Hail and Ride" section of a route.

There are also boarding and alighting points which are "Bus Stop
(Compulsory)". All in-service stage buses on routes that serve
that point must stop there, regardless of whether they have been
flagged [down], or requested to stop by passengers on board.

In practice, however, people don't realise the difference - and
flag down the bus anyway.
