DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a rear combination lamp according to the present invention will be described below with reference to FIGS. In the drawing, the same reference numerals as those in FIGS. 3 and 4 indicate the same components. The rear combination lamp of the present invention in this embodiment is obtained by applying a red clear coating 7 to a dummy portion 6 on the inner surface of the lamp housing 1. The red clear coating 7 is formed on a surface (inner surface) of a base material (a base material, for example, a synthetic resin such as BMC) of the lamp housing 1 by a base coat coating film (not shown, for example, a transparent coating).
Liquid acrylic type), an aluminum vapor-deposited film (not shown) is applied on the surface (surface) of the base coat film, and a top coat colored coating is applied on the aluminum vapor-deposited film (surface). It is applied as a film.

The red clear coating 7 is, for example,
Color clear coating film, one-pack acrylic type,
Or, it consists of a two-liquid urethane type. That is, the red clear film 7 as the top coat colored coating film is formed by coating a varnish made of an acrylic resin or a polyol resin having excellent heat resistance and weather resistance with an organic pigment as a coloring agent (for example, red is quinacridone red or the like). Yes) and inorganic pigments,
It is obtained by sticking, dispersing and coloring. Since the red clear coating 7 has high transparency, even if it is applied to the surface of the dummy portion 6, the high luminosity of aluminum deposition is not impaired. In addition, 3 to 25 in consideration of the color tone density.
