The Solar Road Stud with Shank — Yellow is a permanent, shank-embedded solar pavement marker delivering yellow Super Luminosity LED illumination combined with a prismatic 2-way reflective system. Built from polycarbonate and aluminium, powered by a robust 1800mAh NiMH battery and a 3.25V solar panel, this stud is engineered for long-term, maintenance-free operation on highways, expressways, and critical road infrastructure. The yellow LED colour makes it the definitive choice for centre-line marking, lane guidance, and cautionary delineation on permanently surfaced roads.
