Abstract
A decorative light string having a bulb shunt system is described. The light string includes a plurality of light bulbs positioned within their respective sockets along a power line and in a series circuit. The shunt system includes at least two shunt members associated with each bulb/socket combination wherein a first shunt is positioned within the bulb envelope while a second shunt is positioned outside of the envelope, either in association with the lamp holder or within the socket. The combined initial resistance of the two shunts is preferably greater than the resistance of the bulb filament and the system is configured to shunt the electric current passing through the bulbs in the event of filament breakage and, in one embodiment, in the event the bulb member is removed from its associated socket.
