Nixie tubes - those vacuum tubes that display a single digit or character on glowing wires - were commonplace in the 1950s and 60s but were superseded by LEDs. They’re still made in the Czech Republic, bought mostly by hobbyists to build retro gadgets. I have a few myself that I haven’t gotten around to using.
Weren’t they superceded by LCDs not LEDs? The whole big thing with Nixies was that you could display digits but if one filament burned out (which it relatively quickly did) the whole bulb was bad and even then you had to pump power into them and use these complicated plugs.
Enter LCDs, they take ages to burn in, you can run them off a coin battery for literal years, and they’re a dozen times cheaper to make.
