Sounds very /360-ish :)
Well, sort of the same idea, but not that close. The 360
had metal cases with the pins in a plastic rear piece, and a
loose wired bulb inside, and a plastic front that could be
colored.
The later PDP bulbs had a bare bulb with a molded plastic
fitting at the back. I don't remember whether the bulb had
the big pins embedded in the glass, or the pins were
attached to thin wires and then the joint was embedded in
the plastic.
There were a lot of commercial bi-pin base bulbs made back
in the 1970's.
