A string set of series-connected incandescent bulbs in which substantially all of the bulb filaments in the set are individually provided with a shunt in their respective socket. If flasher bulbs are used in the string, they will twinkle off and on when the operating potential is applied. The flasher bulbs are provided with internal shunts to prevent all of the bulbs of the string from flashing on and off in the event of a failure of the shunt in the socket of the flasher bulb.
