It is visually recognized by the blurring effect of the color development. In other words, when the light beam L1 is incident from the outside when the light is not lit, the surface of the outer lens 6 is colored from the center to the periphery by the reflective action of the reflective coating 9 of the inner lens 7, and is colored integrally with the outer lens of the vehicle body or the adjacent lamp device. The color develops in a gradually changing color tone. Furthermore, when the light is turned on, the luminous flux L2 emitted from the light source 5 is transmitted through the gap 17 between the reflective coatings 9.
If the reflective film 9 is made of a semi-transparent mirror surface, the outer lens 6 is illuminated through the reflective film 9, and the light acts as a marker light.

Since the lamp device according to the present invention is configured as described above, when configured as a marker light for a car, for example, when the lamp device is not lit, light entering from the outside into the outer lens can cause interference between the lens devices or the boundary between the vehicle body and the outer lens.
