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.

I'll bet it's a solid state GE from the early 1970s. They included the
bulb as a high-voltage indicator. This was to deter arcing with a
screwdriver as a test.
