Never heard of such a thing. I use insulators at each end, and in the
old days I used a neon bulb or a 12V tail light bulb as a bleed off. I
went to gas discharge tube arrestors a long time ago. The 12V bulb made
a really nice light show on winter days when the wind was really going.
What kind of buld exactly is a "12V tail light bulb"?
An automotive 12 volt, 5 watt bulb (globe) with (usually) a bayonet
fitting. You can get bulbs that have dual filaments, one filament for
tail lights, the other for brake or indicator lights. The
brake/indicator light filament has a higher wattage rating (21 - 25
Watts) so the bayonet typically has staggered locating pins. This
prevents the higher wattage rating being used as the tail light filament.

New technology is seeing the incandescent bulbs being superseded by LED
arrays.
