Therefore, in the case of a rear combination lamp 1 without a rear fog lamp, the entirety can be recycled.

However, in the case of a rear combination lamp with a rear fog lamp, an aluminum deposition film is formed on the surface of the rear fog lamp reflector 9 and the rear fog lamp reflector 9 is formed.
Is housed in the housing 7, and the entire periphery of the lens 6 c is welded to the front peripheral edge of the housing 7. Therefore, depending on tools such as service tools, the rear combination lamp 1 cannot be disassembled and the rear fog lamp reflector 9 cannot be taken out. Therefore, in the case of the rear combination lamp 1 with the rear fog lamp, it is determined that the entire lamp cannot be recycled.

[0011] Further, in the case of the rear fog lamp, the reflector is doubled, and the number of parts increases, and the weight increases, which is disadvantageous in terms of fuel efficiency.

In view of the above, it is an object of the present invention to provide a rear combination lamp in which a rear fog lamp reflector can be easily removed even in the case of a rear fog lamp specification.

A lens mounted to cover the other end of the housing, wherein the rear fog lamp reflector includes an aluminum thin film on a surface facing a lamp bulb, wherein the rear fog lamp reflector includes a housing. This is achieved by adopting a configuration in which it is detachably attached to the device.
In the rear combination lamp according to the present invention, it is preferable that the reflector for the rear fog lamp is detached from the housing, and a reflector for a normal tail stop lamp can be mounted instead.

According to the above configuration, since the reflector for the rear fog lamp having the aluminum thin film is detachably attached to the housing, it cannot be recycled by using a tool such as a service tool at the time of recycling. The reflector for the rear fog lamp can be easily removed, and the other parts, namely the housing and the lens, can be recycled. This allows
The recyclability of the rear combination lamp with the rear fog lamp is improved, and since there is no reflector for the tail stop lamp, the structure is lighter, which is advantageous in terms of fuel efficiency.

When the reflector for the rear fog lamp can be mounted in the state where the reflector for the rear fog lamp is removed from the housing, a rear combination lamp without a rear fog lamp and a rear combination lamp with a rear fog lamp are provided. The lamp can be assembled using a common housing and lens, and the cost of parts can be reduced by sharing parts.
