Yeah, at our company our engineers have weird ideas too...
Things like:
led off = subsystem disabled
led green = (sub)system up and running
led green (blinking) = activity
led yellow = warning
led red = error/critical
I mean, how do you think up things like that?
And then they have the guts to put in something like 10-12 of those leds
in a matrix and put text next to it like "Power", "Link", "Activity", etc.
And to make it worse, it actually makes sense to our users! ;-þ
