SR-T24 | Ireland Tunnel Lighting Road Stud

The SR-T24 Tunnel Road Stud is a high-intensity, hardwired LED guidance device developed specifically for tunnel environments and enclosed roads. Designed to ensure maximum visibility in low-light or high-risk zones, the SR-T24 offers exceptional clarity through its customisable LED configuration, enabling clear unidirectional or bidirectional guidance with visibility up to 1km.

With a robust anodised aluminium body and IP68/IK10 protection, the SR-T24 is purpose-built for the harsh demands of tunnel systems — from daily vehicular traffic to emergency egress routes. Powered by 24V DC or 230V AC and compatible with external controllers for flashing or sequential modes, this advanced road stud is trusted across Ireland’s tunnel infrastructure for its safety, clarity, and reliability.

Technical Review

The SR-T24 is a flush-mounted, cabled road stud with customisable LED layout and colour output. Available in unidirectional, bidirectional, or arrow-top configurations, it delivers clear guidance in even the darkest environments — with green, amber, red, blue, or white LEDs.

Its compact profile (100x88x32mm) allows for seamless integration into tunnel flooring, while the anodised and lacquered aluminium body withstands corrosion, water ingress, and physical impacts. With low power consumption (from just 10mA AC), this stud is energy-efficient and UPS-compatible for guaranteed performance during power loss events.
