At the start of the decide, certainly - but by 1980 I would have thought
that the cost had come down significantly, and LEDs surely had better
longevity than panaplex-type devices, so I don't know what the reasoning
for using them would have been.
Thinking about it though, I'm not sure that I've ever seen a gas (petrol)
pump with LED displays, although I don't know why they wouldn't exist.
Mechanical displays seemed to be the norm back in the day, to be replaced
by LCD displays in the nineties and 2000's.
