I've noticed by the "bay" of 4 seats near the front of the bus on
Mercedes Articulated buses there is a button which reminds me of the
door open buttons on mainline trains. They only seem to light up when
the bell has been pressed.

Does anyone know what they do?

Aren't they simply a bell push? This saves people having to stand up or
stretch to a push mounted on a vertical stanchion. I'm guessing but I
assume they illuminate to show that the bell has been pushed elsewhere
and there's no need to bother.

That's exactly how it worked on the bendy I rode on today.
