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 

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.
