Rail Signal LED Road Stud (TS-SR-50-RYG)

Rotatable, Stainless Steel


General Description

Signaling systems are fundamental to the safe and efficient running of railway operations. The systems are used to signal the permitted running speed to the train operator. Our in-pavement, recessed fixtures provide signaling without obstructing the flow of pedestrians and vehicle traffic in urban environments.

Our TS-SR-50-RYG stainless steel road stud features a durable, low maintenance design with outstanding visibility during the day and at night.


  • Use with traffic control devices.
  • Robust construction, suitable for harsh conditions.
  • Snowplow resistant.
  • Ability to rotate after installation.
  • Only .16″ (4mm) above road surface.
  • Red, Yellow and Green highbright LEDs (1W) with internal lens – used for maximum brightness.
  • Specially developed heat sink to increase LED lifetime.
  • Outstanding visibility during the day and at night.
  • Low maintenance, 100% waterproof.
  • Easy replacement: base (fixed in the pavement), main body (removable).
  • Polycarbonate window protects LEDs.
