Default Dumb TV question

Yes, I'm sure, was a small glass neon bulb soldered to chassis.
I looked through a good many old Sams folders, back into the '70s & '80s but never found a neon bulb in one. Problem is, just because it was near the fly doesn't have to mean it was in the fly circuit. So it must have been in some other circuit. I think it was for spike protection, for whatever circuit it was in.
I'm ready to just forget it, not important.
Thanks to all for replies!

Are you sure it is really a neon bulb? I'm thinking it is possibly a high
voltage spark gap which serves as overvoltage protection... Just my
thoughts. Without seeing it it would be hard to say for sure.

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.
