Moreover, the function of the lamp set is not affected, and the manufacturing cost with respect to the assembling means is reduced.

A fixing portion 16A is disposed on two ends of the board 11A with respect to the positive joint 14A and the negative joint 15A. The fixing portion 16A adopts a breach, a buckle (as shown in FIG. 10) or a screw hole. The fixing portion 16A fixes each board 11A to the frame or the plaque E of the car.
