In addition, a portion of the rear surface 3 of the vehicle body to which the turn signal lamp a is attached may be partially bulged rearward due to restriction of the drawing depth at the time of molding. In such a case, the bulb light hits the bulging portion, and the irradiation of the light to the bent end portion of the inner / outer lens is interrupted. In the area where this light irradiation is blocked, the bulb light travels to the terminal side while repeating total reflection.However, in the case of a turn signal lamp using double lenses of different colors, the green color of the inner lens is insufficient. Since the mixed light is mixed, it has a reddish color.

In FIG. 1, reference numeral 1 denotes a turn signal lamp as a vehicle signal lamp, and its bent end is set on a rear surface 3 of the vehicle body along a side surface 2 of the vehicle body. As shown in FIG. 1, the turn signal lamp 1 has a housing 4 fixed to a rear fender panel 5 forming rear surfaces 2, 3 on the vehicle body side. The rear fender panel 5 has a portion adjacent to the vehicle body side surface 2 of the vehicle body rear surface 3 bulging rearward due to the restriction of the drawing depth at the time of molding. In the housing 4,
A bulging portion 7 is formed at a position corresponding to the bulging portion 6 of the rear fender panel 5. A valve 8 is attached to the housing 4 using a fixture 9.

At the ends of the inner and outer lenses 10, 11, a bulb 8 is provided.
Is interrupted by the bulging portion 7 of the housing 4 and is no longer irradiated. Of these, in the non-light-irradiated portion of the outer lens 11 (the portion in front of the irradiation limit L), the bulb light travels to the terminal side while repeating total reflection, and conventionally, the green color of the inner lens 10 is changed. Insufficient mixed light resulted in a reddish color,
In the present embodiment, since the thick part 12 is provided in the inner lens 10 and the green light of high density is made incident on the end of the outer lens 11, the green and pink light are mixed at an appropriate ratio. Amber emission can be obtained.

Since the light transmission length of the inner lens 10 is increased and the density of the green color incident on the outer lens 11 is further increased, not only the discoloration hardly occurs, but also the thickness due to the heat shrinkage at the time of molding the inner lens 10. , The desired colored light can be easily obtained.
