But then there is the matter of getting the signals out to the LEDs.  Do
you want to use 1000s of wires, or have some kind of fanout protocol?
Either way is a pain.

Of course the whole problem is fictional, but if they are really
indicators, addressible LED's and some CAN bus stuff seems like the way
to go.
