A string of light uniquely matches light bulbs to sockets based on a structure. Each light bulb has a bulb and a base. The bulb has a bottom, and the base is connected to the bottom of the bulb and has a thread and a central contact protruding coaxially from the base. Each socket has a recess to hold the light bulb and has an inner sidewall, a thread formed on the inner sidewall, a resilient contact mounted longitudinally on the inner wall and abutting the outer surface of the base and an central contact in the recess and selectively abutting the central contact of the light bulb depending on the structure of the light bulb and the socket.
