Try an NE2 bulb? That's what used to be in the old starters.

ERRRRRRR! Wrong! I would suggest you find an old florescent starter
and take it apart, carefully break the glass off the silvered bulb
and you will find a heat activated bi-metal switch. A little searching
of The Interweb will help you learn how it works.

The bimetal strip starters have four pins.Two for the resistor & two
for the bi-metal strip/switch contacts. They haven't been made for
years.

Glow switch starters have bimetal strips inside their bulbs.
