This utility model relates to a decorative light, and particularly, to a decorative light capable of avoiding an open circuit condition on an entire string of bulbs that operate in series when an individual bulb is removed. The decorative light comprises a socket, a bulb base, a bulb and two terminals, wherein the socket is provided with a retainer therein, which has an opening laterally extending therethrough, and an elastic, conductive ring or coil with a thickness smaller than a width of the opening is disposed within the opening. When the elastic ring or coil is in a natural state, the elastic ring extends outside the retainer through the opening at two sides of the retainer. The bulb base is further provided with an inserting partition at the bottom thereof. The elastic conductive ring has two states: one is a separating state where the bulb base is inserted into the socket. In this first state, the inserting partition of the bulb base separates one side of the elastic ring or coil from the corresponding terminals. The other state is a conducting state of the two terminals when the bulb base is removed from the socket. In this second state both sides of the elastic, conductive ring or coil provide contact with the two terminals respectively. This utility model provides a decorative light capable of preventing failure of the complete string of bulbs when any bulb is removed.
