ABSTRACT:
A decorative bulb includes:
a bulb socket, a pair of doubly-sticking conducting plates inserted in the socket to electrically connect a pair of filament leads with two electric wires, a sealing plug sealing the socket bottom and squeezing the two wires with the two conducting plates for ensuring a better electric contact between the wires and the conducting plates, and a bulb having an annular groove formed on a bulb periphery engaged with a ring extension formed inside the socket, so as to obtain a decorative bulb with stabler mounting of the grooved bulb within the ring-extended socket for water-proof purpose and to save production cost by eliminating a base as conventionally embedded between the bulb and the socket.
