SR-20C – Hardwired Road Stud | Ireland Intelligent Traffic Management Solution

The SR-20C is a low-profile, hardwired LED road stud designed for safer traffic guidance in low-visibility zones, bends, crossings, and delineation points. With just a 15mm rise above the road surface, it offers vehicle-friendly performance while delivering high-intensity, directional illumination day and night.

This rugged road marker is equipped with up to 4 high-output 5mm LEDs and features an internal prismatic system to enhance light dispersion. Designed to handle up to 20 tonnes of pressure and IP68/IK10 rated for weather and impact protection, the SR-20C is ideal for long-term use on Irish roads. Powered by 12V or 24V DC (with solar compatibility) and connectable in series, it provides a reliable, low-energy lighting solution for modern infrastructure.

Technical Review

Engineered for versatile traffic applications, the SR-20C supports both unidirectional (1 or 2 LEDs) and bidirectional (2 or 4 LEDs) lighting configurations. Its LED colour options—white, warm white, red, amber, green, or blue—make it suitable for traffic control, pedestrian zones, cycle paths, and visually guided transitions at crossings or bends.

The SR-20C can be installed flush with a minimal 15mm height, ensuring smooth passage for vehicles. Multiple units can be connected in series for extended delineation, and lighting modes like flashing or sequential can be activated using external controllers. With a working temperature range from –25°C to +85°C, it’s built for Irish road conditions year-round.
