SR-48 – Stainless Steel Hardwired Road Stud | Ireland Intelligent Traffic Management Solution

The SR-48 is a heavy-duty stainless steel LED road stud engineered for permanent installation in areas exposed to regular heavy vehicle traffic. With high mechanical resistance up to 90 tonnes and compatibility with snow ploughs, the SR-48 is ideal for harsh Irish environments, including industrial access roads, tunnels, ports, and airside applications.

This hardwired road stud provides high-intensity bidirectional LED visibility with up to 1km range in both daylight and nighttime conditions. Designed to last, it features a corrosion-resistant stainless steel top with a sealed polycarbonate light window and an anodised aluminium base for maximum durability. Powered via 12V or 24V DC, the SR-48 is also compatible with flashing and sequential operation via external controllers.

Technical Review

Purpose-built for Irish roads under heavy use, the SR-48 combines robust mechanical integrity with flexible lighting performance. Each unit is equipped with 16 high-output 5mm LEDs in a bidirectional layout, enclosed in a waterproof and impact-resistant housing (IP68 and IK10).

It operates reliably across a wide temperature range (–25°C to +85°C) and can be customised with different LED colours per light window. Its flush-mount installation, rugged body, and optional flashing modes make it ideal for areas requiring 24/7 visibility and long-term durability.

Also available in the SR-48P version, which features ultra-bright 1W power LEDs, enhanced optics, and a heat sink for greater light intensity and longevity.
