But in 1978 I wired the 2 bulbs in the each of the EXIT

Congratulations, you probably bypassed a safety feature. If they're in
parallel, if one burns out the other keeps going. In series, if one
goes they're both out, and the exit sign is no longer visible.

And what if both burn out in parallel, which they eventually will -
and eventually is measured in months or, at best a low number of
years.
With the series string, if one blows it will likely be a decade or 2
or 3.
