Is it true that some subway 110V incandescent light fixtures used
left-hand threads to deter bulb snatchers?

[TELECOM Digest Editor's Note: I know that in Chicago long ago, all
the station lighting and platform lighting they did left hand threads
to inhibit people from stealing the bulbs if they needed them at their
own houseand also the voltage was sufficiently different the bulbs
generally would not work in your home electrical outlets anyway. PAT]
