The stud body comprises an outer wall(410), an end protrusion(411), and wheel contact parts(420,420b). Screw holes(421) are formed on one wheel contact part, and a light emitting unit(200) is formed in the other wheel contact part. A storage battery is installed in the stud body. A stud mounting unit(610) and a support protrusion(611) are formed in the stud external case. The stud external case protrudes the wheel contact parts from the top of a road surface.
