2. Description of the Related Art FIG. 7 shows an example of the configuration of a conventional headlight 90 that also serves as a side-light and is used for a headlight light source 91 such as a halogen bulb. A parabolic reflector 92 having a headlight light source 91 as a focal point is provided. A light source attachment hole 92a for a sideways light is provided at an appropriate position of the reflector 92, and a light source 93 for a sideways light is provided so that the filament is positioned in the reflector 92 through the light source attachment hole 92a for a sideways light. Is installed.

A reference numeral 94 in the drawing is a hood. The hood 94 is directly radiated to the outside by the direct light from the headlight light source 91, which causes a driver of an oncoming vehicle to be dazzled. In order to prevent the light from being emitted, the light emitted from the headlight light source 91 is provided so as to block the light that goes toward a portion other than the reflecting mirror 92. Further, in recent years, the lens 95 is often transparent, and the reflecting mirror 92 and the hood 94 are seen through. Therefore, the portion visible from the outside of the hood 94 is the same as the reflecting mirror 92. Brightness treatment such as vapor deposition is performed.

By doing so, for example, at night,
When the headlight light source 91 is not lit, such as when the vehicle is stopped, the entire surface of the reflecting mirror 92 emits light of appropriate brightness by the light from the sidelight light source 93, and the light is emitted to an oncoming vehicle. It will be able to announce the existence of the car.

[0005]

However, in the above-described headlight 90 also serving as a sidelight, which is constructed as described above, firstly, the reflector 92 is provided with a sidelight source mounting hole 92a for the sidelight, and the rear side Since the vehicle width light source 93 is projected into the reflecting mirror 92, in the recent vehicle width light and headlight 90 in which the lens 95 is transparent, the vehicle width light source 93 is visible. However, it causes design problems such as discomfort to the viewer.

Second, since the illuminance is relatively low when it functions as a side-light, the light emitting area greatly contributes to the improvement of visibility. However, in the conventional headlight 90 that also serves as a sidelight, since the sidelight light source 93 provides light only to the reflecting mirror 92,
When viewed from the front, the portion of the hood 94 does not shine,
As shown in FIG. 8, it becomes a substantially donut-shaped optical image, the light emitting area is reduced, the visibility is lowered, and there is a problem that the viewer feels uncomfortable in terms of shape.

Regarding the structure in which the light source 93 for a vehicle width light can be arranged without providing the light source mounting hole 92a for a vehicle width light in the reflecting mirror 92, the same applicant as the present invention filed Japanese Patent Application Laid-Open No. Although the problem is solved by Japanese Patent Application Laid-Open No. 10-116504, the point that the light emitting area is reduced by the hood 94 is not solved in this prior application as well, and the problem is not completely solved.

[0008]

As a concrete means for solving the above-mentioned conventional problems, the present invention comprises a light source for a headlight and a light source for a sideways light provided in an integrated lamp body. In a headlight that also serves as a sidelight of a vehicle, at least one recess is provided in a front portion of a hood that is provided in front of the light source for the headlight and that has been subjected to a glitter treatment similarly to a reflecting mirror. The problem is solved by providing a headlight that also serves as a sidelight of a vehicle, in which a light source for a widthlight is provided at a position where the reflector and the front surface of the hood can be illuminated.
