As shown in FIG. 5, the boat-shaped bulb 110 has a light emitting portion 111 formed in a cylindrical shape and a conical end portion 112 formed in a conical shape along the central axis of the light emitting portion 111 at both end portions 110a. Each electrode 113 is provided at the tip of each conical end portion 112.
As shown in FIG. 6, the wedge bulb 120 includes a light emitting portion 121 and a flat-shaped flat portion 122 in which each electrode 123 is formed on both sides.

Next, the function unit 10 will be described.
The functional unit 10 includes three fixed contact bus bars 11, a pair of valve electrode connection bus bars 20 (hereinafter referred to as a first valve electrode connection bus bar 20a and a second valve electrode connection bus bar 20b), and a switch. A functional unit 30 is provided.

  Each fixed contact bus bar 11 (hereinafter referred to as a first fixed contact bus bar 12, a second fixed contact bus bar 13, and a third fixed contact bus bar 14) is used for switching the lighting on and off. A fixed contact (hereinafter referred to as a first fixed contact 12a, a second fixed contact 13a, and a second fixed contact 14a) connected to a movable contact 37 described later is provided.

The third fixed contact bus bar 14 is connected to a later-described third male terminal 64 via an electric wire W and is grounded via the third male terminal 64.
Each fixed contact bus bar 11 is connected to the electric wire W through the press contact terminal 11a, and is fixed to the bottom wall 40a of the housing 50 through the fixing protruding blade 11b.

As shown in FIGS. 7 and 8, the first valve electrode connecting bus bar 20a and the second valve electrode connecting bus bar 20b, which are paired, are adjusted by adjusting the installation interval, thereby forming the boat-shaped valve 110 or the wedge valve 120. The two electrodes 113 and 123 are electrically connected.
The first valve electrode connecting bus bar 20a and the second valve electrode connecting bus bar 20b are symmetrical with the surface 22b on which the electrode 113 of the boat-shaped valve 110 of the boat-shaped valve connecting portion 21 to be described later abuts facing each other. It is formed to become.

The valve electrode connection bus bar 20 will now be described in more detail using the second valve electrode connection bus bar 20b.

And a wedge valve connecting portion 22 that is in contact with an electrode 123 formed on the flat portion 122.
The boat-shaped valve connecting portion 21 has a plate shape with an outer rectangular shape.

The wedge valve connecting portion 22 is configured so that the flat portion 122 is sandwiched and is in contact with the electrode 123 of the wedge valve 120, and the end portion 110a of the boat-shaped valve 110 can be inserted therebetween. 21 is formed by bending both edges 21aa of one end 21a in the longitudinal direction.
The wedge valve connecting portion 22 has a pair of cantilevered elastic pieces 22c in which the end portion 22a on the insertion side of the boat-shaped valve 110 or the wedge valve 120 is a free end and the distance between the opposing surfaces 22b is changed. Thus, at least one of the pair of cantilever elastic pieces 22c is brought into contact with the electrode 123 of the wedge valve 120.

Further, the valve electrode connection bus bar 20 is extended to the other end 21b in the longitudinal direction of the boat-shaped valve connection portion 21, and is fixed to the connection portion 23 connected to the electrical wiring and the housing 40 as the attachment destination.
