A bulb socket which can receive both a round base bulb and a wedge base bulb. A bulb-receiving portion (23) is provided in its interior with a pair of bulb insertion grooves (26) which are symmetrically spaced at an angle of 180.degree.. The groove (26) has a guide portion (27) extending axially from an open edge to an inner part and an engaging portion (28) turning circumferentially at an inner end of the guide portion (27). A pair of projections on the base of the round base bulb are inserted into and secured to the bulb insertion grooves (26), respectively. Opposite side edges of a base of the wedge base bulb are inserted into and secured to the guide portions (27), respectively. The bulb-receiving portion (23) is provided in its interior with contact piece insertion grooves (30a, 30b) which receive a pair of positive and negative contact pieces for the round base bulb and a pair of positive and negative contact pieces for the wedge base bulb and which are disposed symmetrically at positions shifted circumferentially from the respective bulb insertion grooves (26).
