Only when the manufacturer applies for certification of the entire
aircraft does the light bulb and socket get its official paperwork.

Maybe true... but that speaks to the approval process itself (and
whether or not the FAA approval process is stupid for any given part).
I agree that sometimes it seems stupid. But sometimes it's not, and
it's a slippery slope to decide which rules don't apply to you because
you are smarter than the FAA.

Back to one sip of beer seven hours before takeoff, vs two glasses of
beer eight hours before takeoff. One's legal, one's not. The one that
is not is probably safer than the one that is. But how far down the
line are you willing to go? And once you decide that, why not "just a
little" further?
