A light bulb socket has a main body comprising inner threads, a longitudinal recess, a bottom plate, a through hole formed on the bottom plate, and a flange which is on top of the bottom plate surrounding the top edge of the through hole. The first conductor is inserted in the longitudinal recess. The second conductor is inserted in the through hole. Two grooves are formed in the periphery of the through hole. The second conductor has a round top, a neck, two slant fins, a transverse bar, and an end tip. A gap is defined by the round top. The second conductor is inserted in the through hole beneath the flange.
