I worked on a car stereo project 7 or 8 years ago where we used
exactly this concept (we called it "contextual luminescent feedback").
At the time we couldn't find examples that really did this in any sort
of sophisticated way either, but we ran with it anyway because we
thought it was compelling & appropriate for what we needed. For all
sorts of reasons it never was built, but as it played out in the
detailed design, it seemed pretty successful.
There are some simplistic examples (some vending machines indicate the
availability of an item by lighting up the button that you press to
get it), but I think that's probably not quite the same as what you're
describing.

Hi all,
I'm considering a pattern in which each
button lights up when it's active/available and gets dark when it's
inactive/unavailable.
There are certainly many devices with buttons that light up in order
to reflect the on/off state of a particular feature (e.g. caps lock
key), or of the device itself. However, I can't think of any
examples where lighted buttons reflect availability rather than
state.
