Embedded Solar Road Stud SIG 31D

Solar Road Studs SIG 31D are a highly efficient source of light designed for road marking and to increase road safety. They are made using the highest quality components and are in compliance with EU certification.

Description : Embedded Solar Road Stud SIG 31D

The solar road stud Elements SIG 31D combine the functionality of reflective markers with the extremely high efficiency of LED lighting.

They provide high-quality active road marking, fully autonomous - powered only by solar energy.

They are perfect for wet conditions, where the performance of traditional retroreflectors is reduced (car lights disperse in water rather than bounce back from the markers), while the light emitted by the LEDs remains visible.

The highly intensive LED lighting pierces the fog.

It is an additional lighting, which increases safety on roads with poor or no street lighting.
LED light already lights up at natural light intensity of 150-350 LUX, which makes the SIG 30D Solar Road Studs operate not only at night but also during heavy rain, fog, dusk.

The very low profile of Solar Road Stud SIG 31D  eliminates the risk of mechanical damage during snow removal and increases pedestrian safety (e.g. on crossings, parking lots, driveways etc.)

Light parameters:

  • Glowing time: 180 hours.


  • Body diameter: 135 mm
  • Body height: 50 mm
  • Weight: 710 g


  • Ultra-high intensity LEDs combined with retroreflectors provide excellent light performance - the markings are already visible from 800m
  • The waterproof (IP68), very strong polycarbonate housing ensures long-term durability of the markings.
  • The light automatically turns on and off already at a natural light intensity of 150-350 LUX.
  • Fully autonomous light source powered exclusively by solar energy is economical and maintenance-free. Instead of regular NimH batteries, the Solar Road Studs SIG 31D use 2 high-capacity supercapacitors, which extends the life of markings from several years
