Our doorbell is a conventional 'Ding-dong' solenoid 6V battery powered

So I could hear it in the garden it's near the back of the house and
so because of the double glazing, you often (depending on other
outside noise levels etc) can't hear it outside the front door.

Some of the delivery drivers (and a couple in particular) *also*
either rap the letterbox or tap the glass (one quite 'energetically
that makes the dog think he was an aggressor and he tells him so when
I open the door). ;-)

So, without putting any significant extra load on the battery system
or replacing the bell etc, is there an existing solution that provides
positive feedback for a successful press of the doorbell or can anyone
think of something that could be made / done that would provide such?

Couldn't you replace the button with an illuminated one? The kind where
the light goes out when you press the button (because it's wired across
the contact). You could probably DIY (incandescent or LED).
