The picture shows the amber solar road stud just completed by NOKIN factory. This solar road stud is also the most common one on the road. Its advantage is that it is cheap and can be used on both sides of the road, the edge of the park flower pond, the lane markings, and so on, but due to theShenzhen Nokin Traffic Facilities Co. compression resistance of this solar road stud, it is not suitable for the center of the road.
