14, the light enters the prism unit 43 from the bottom surface, and further exits from the front and rear side surfaces 422 and 423. The light is on the front and rear sides 42
When the light exits from the light source 2,423, the light is refracted in a direction substantially parallel to the road surface 3 and a light beam of a sufficient amount reaches far and can be visually recognized from human eyes such as a driver's seat. Since the light from the light source 5 is collected in the vertical direction, the brightness increases. In particular, light source 5
Is multiplied, the luminous flux is doubled, and the visibility is considerably improved as compared with the case of one stage. Although there is a problem of chromatic aberration when refraction is used, no problem occurs because the light emitting diode basically has only a single wavelength.

At night, the yellow light-emitting diode (mainly λd = 590 [nm]) is sufficient for visual recognition. However, at daytime, a single color of yellow causes color skipping and poor visibility. Therefore, as described above, a red-orange light emitting diode (mainly λd = 615-620 [n

きる。On the other hand, since the cover member 4 is transparent, a part of the light emitted from the light source 5 is irregularly reflected inside the cover member 4,
The entire cover member 4 appears to shine, and visibility at a position shifted from the optical axis (light ray path) of the light source 5 is improved. In other words, for a driving vehicle traveling on a road, the road stud 1 can be confirmed by light emitted in the horizontal direction through the prism portion 43 from a distance, and deviates from the optical path of the light beam passing through the prism portion 43 as approaching the road stud 1. However, since the entire cover member 4 is illuminated, the road stud 1 can be clearly recognized.
