The peripheral edge 71 a of the lens 71 has a step portion, and the step portion is fitted to the peripheral edge 68 c of the concave portion 68 of the lid 65.
The light components such as the recess 68 and the substrate 72, the LED 74, and the lens 71 accommodated in the recess 68 are referred to as a taillight 77.

A manufacturing process of the taillight 77 according to the present embodiment will be described.
First, a lid 65 having a recess 68 is formed by molding with polycarbonate or the like. At this time, the attachment portion 73 having the coupler 70 and the screw hole 73a is formed in the recess 68.
Next, a substrate 72 on which circuit components and LEDs 74 are mounted is assembled in the recess 68. At this time, the substrate 72 is attached to the recess 68 in such an arrangement that the lead wire 76 is led out from the coupler hole 69 to the coupler 70.
Next, the peripheral edge 71a of the lens 71 and the peripheral edge 68c of the recess 68 are aligned, the lens 71 is fitted into the lid 65, and the lens 71 is attached to the recess 68 by ultrasonic welding. Thus, the tail light 77 is formed on the lid 65.

The light structure of the taillight 77 according to this embodiment described above has the following effects.
Since the taillight 77 has a configuration in which lamp components such as the substrate 72 and the LED 74 are directly assembled in the recess 68 formed integrally with the lid 65, the number of components is small, and the work process can be reduced.
Conventionally, the light unit is fitted together with the case in the housing portion formed in the vehicle. However, the taillight 77 according to the present embodiment has the concave portion 68 that serves as the case and the housing portion in the conventional manner. Therefore, the space can be reduced as compared with the conventional structure in which the storage portion is configured according to the size of the light unit. Therefore, the storage space for the utility box 63 can be secured more by reducing the recessed portion 68 that protrudes into the utility box 63.
In addition, since the taillight 77 is configured at the upper end and the rear end of the utility box 63, the storage space is not divided as compared with the case where it is provided at another position such as the center in the vertical direction, and large equipment such as a helmet can be obtained. Can be stored. Further, when the taillight 77 is formed at the lower end, it is necessary to consider the arrangement so as not to obstruct the lid 65 when storing a large baggage. Can be stored.
By aligning the peripheral edge 71a of the lens 71 with the left and right edges of the lid 65, the taillight 77 can be enlarged. Further, the lens 71 is mounted flush with the lid 65 and has the same surface as the surface around the recess 68, so that there is no protrusion and the appearance is improved.

Note that the present invention is not limited to the above-described embodiments, and it is obvious that the embodiments can be appropriately changed within the scope of the technical idea of the present invention.
The number, position, shape, size, and the like of the above-described constituent members are not limited to the embodiment, and can be set to a number, position, shape, size, and the like that are suitable for carrying out the present invention. For example, the number and arrangement of the LEDs 74 are not limited to the above embodiment, and other numbers and arrangements may be used.
In the above embodiment, the configuration in which the recess 68 is formed in the lid 65 of the utility box 63 has been described. However, the recess 68 may be formed in another position or member such as the rear fender 61, for example. Moreover, although the case where it provided in the back of the vehicle 1 and used as the taillight 77 was demonstrated, it can also be applied to other positions and uses, for example, it is provided in the front and used as a headlight.
Although the case where the vehicle 1 is an ATV has been described in the above embodiment, the present invention may be used for other motorcycles, motorcycles, bicycles, and the like.
Moreover, although the case where LED74 was attached facing back was demonstrated, another direction may be sufficient, for example, the board | substrate 72 may be distribute | arranged substantially horizontal and LED74 may be arrange | positioned facing down.
Although the case where the board | substrate 72, LED74, etc. are accommodated as a lamp component in the said embodiment was demonstrated, it is not restricted to these, It can apply also to another component. For example, a lamp or the like may be used as the light emitter instead of the LED 74.
In the above embodiment, the configuration in which the lens 71 is attached by ultrasonic welding has been described. However, the lens 71 may be formed so as to be fitted to the peripheral edge 68c of the recess 68, and the lens 71 may be attached by being fitted to the recess 68. Good.
