The Cast Iron Round LED Road Stud is a robust, high-performance auxiliary device designed for integration with traffic signal systems to significantly enhance road safety. It provides clear, synchronized visual guidance for both drivers and pedestrians at crosswalks, intersections, and construction zones. With a durable cast iron body and high-strength polycarbonate lens, it withstands heavy vehicle loads up to 80 tons and operates reliably under extreme weather conditions. Featuring an IP68 protection rating, the stud remains fully functional in wet, flooded, or snowy environments. Its ability to display multiple colors—red/green for signal synchronization and yellow/white for hazard warnings—makes it an ideal solution for modern smart city traffic management systems.
