ABSTRACT:
A string set of series-connected incandescent bulbs adapted to being connected to a source of alternating-current operating potential and in which all of the bulb filaments in the set are individually provided with a non-avalanche shunt circuit which substantially maintains the rated voltage of the bulb across each of the bulb sockets whether or not an operative bulb occupies its respective socket and whereby the illumination of each remaining operative bulb continues to be substantially unchanged and substantially the same rated current continues to flow through said string set despite the absence of a plurality of bulbs from their respective sockets.
