intermittent single beep

You thinks wrong, at least on the earlier type 44 autochecks, one light
bulb per indicator.  I took one of the old style autocheck displays
apart.  Wow, there are 12 bulbs in there (11 without Engine Check
Display).  Three focusing plates with 12 lenses in each one.  Each bulb
when lit illuminates a micro-slide which focuses through the optical
array to the front of the autocheck display which is a rear projection
screen.  Cutting edge and expensive stuff in the day.  The piece that
keeps the bulbs from bleeding light is a heavy piece of precision
machined steel.
