It’s getting harder and harder to find the “old style” bulbs nowadays …. Can Halogen bulbs work in a dim bulb tester ? they do have a filament , but it’s a different set up in the bulb ….
Been thinking about this. Worst case might be to add a second socket and use two 120 volt bulbs in series. Probably the cheapest solution.
Depending upon where your located, this may help:
