Another thread on here mentions the NE-2 neon bulbs. I remember those
going back to the 60s. They have never changed, but worked well for
testers or indicators if you did not want brightness.

But I always wondered, was there a NE-1, or a NE-3? I always wondered
why they are called NE-2? I have never seen any other number after the
NE-.

You can still buy an NE-3, it's a long lamp with a "telephone slide
base", designed to be mounted to a panel as an indicator and viewed end-on:
