Improved Safety on the Road

LED MOBILE VMS Improved Safety on the Road

Mobile variable message signs are used world-wide by various construction, maintenance and service companies as well as enforcement agencies. These flexible signs improve road safety by keeping drivers informed with the latest road conditions, obstacles and congestions.

LED mobile Variable Message Signs consist of:

  • warning trailers
  • signs for road maintenance trucks
  • temporary variable message signs
  • signs for police and other intervention vehicles

Customised technology.

Our patented lens technology, which offers an unrivalled performance, ensures the best visibility even in adverse conditions, especially when the sun is low in the sky. The external dimensions, mounting, service access, electrical supply and data interface can be flexibly adapted to meet the requirements. The lower power consumption for all freely programmable and full colour applications means that operating costs and CO2 emissions are reduced by up to 95%, ageing effects are prevented and maintenance and spare parts costs are minimised.
