What is the purpose of the small neon bulb by the flyback on older TVs? (I haven't noticed it in any modern tvs.)
Someone asked me that the other day and I couldn't answer! Seems like I used to know (I'm an old-timer) but can't remember.
Thanks.

Could be a voltage reference (~60 - 90 V), voltage drop or translation,
a hysteresis element in a multivibrator, clamp or even indicator of
some circuit's status.
