The opening (11) is defined through the distal end, communicates with the cavity and may have a noncircular and nonsymmetrical shape. The proximal end has a through hole (12, 12a). The through hole (12, 12a) is defined through the proximal end and communicates with the cavity. The inner wall is adjacent to the through hole (12, 12a) at the proximal end and may have two tracks (14). The tracks (14) are formed opposite to each other and communicate with the through hole (12) at the proximal end of the base (10), and each track (14) has two sides and two rails (16). The rails (16) are formed on and protrude from the inner wall toward each other. The sidewall adjacent to the proximal end may have two recesses (15a). The recesses (15a) are formed in the sidewall opposite to each other and communicate with the cavity and the through hole (12a) in the proximal end of the base (10a). The cap (70) is mounted in and closes the through hole (12a).
With further reference to FIGS. 3 and 14, the socket (20, 20a) is hollow, may be noncircular and nonsymmetrical, corresponds to the opening (11) in the distal end of the base (10, 10a), is mounted in the cavity of the base (10, 10a) through the opening (11) in the distal end of the base (10, 10a) and has a cavity, an open top, a closed bottom, an inner surface and an LED lead seat (25, 25a). The open top is resilient, communicates with the cavity of the socket (20, 20a) and has a tapered inner edge. The closed bottom has two LED lead holes (24). The LED lead holes (24) are defined through the closed bottom. The inner surface is cylindrical and has an annular groove (21, 21a) and a positioning protrusion (23). The annular groove (21, 21a) is formed in the inner surface near the open top. The positioning protrusion (23) is formed on the annular groove (21, 21a) and has a flat surface. The LED lead seat (25, 25a) is a rectangular parallelepiped shape, is formed on and protrudes coaxially from the closed bottom and has four longitudinal surfaces and two seats (252, 252a). The seats (252, 252a) are formed respectively on two opposite longitudinal surfaces and correspond respectively to the LED lead holes (24), and each seat (252, 252a) faces the corresponding track (14) and has an inner surface.
