Product advantages

The main advantages of S–4 cabel are:

  • High visibility of the reflector up to 1000 m
  • Low maintenance costs of labelling dangerous spots on roads
  • Energy saving system allows full time working LED system
  • Energy-saving system capable of operating LED lights up to 380 hours on a single battery charge
  • Possibility of flexible programming of the length of light and the power of LED light
  • Possibility of installing two-color LEDs (eg .: 1 LED white, 2 red LEDs on one side)
  • Possibility to connect the S-5 to the night or motion sensor
  • it can be used in the places where is impossible to use photovoltanic panel
  • Cable power system allows aplication S-5 in places, where the charging of accumulator by photovoltaic panel is impossible


S-4 cabel is recommended for the marking of highly dangerous main roads and motorways:

  • Dangerous sections of streets in towns where a lot of accidents happen
  • Low speed bumps ahead of crossroads
  • Tunnels
  • Bridges
  • Active  pedestrian crossings
