Many companies trust us

Here are some of the companies that appreciate working with us and for whom we provide high-quality services.


Nissen is one of the world’s leading providers of road safety solutions. The company was founded more than 100 years ago.

In 1914, the company’s founder Adolf Nissen began developing ignition systems for automobiles and registered patents in several countries for this purpose. In the mid-1950s, Nissen Elektrobau GmbH entered the traffic management industry.

The breakthrough came with the development of the first electric warning lamp. Further innovations, such as control devices for automated systems, confirmed the company’s reputation as a pioneer of progress. Nissen expanded over the following decades – both in its original location and by opening branches in England, Switzerland and other countries.

Nissen not only contributed to the development of innovative technologies such as LEDs in road safety, but also played a significant role in the unification of road safety regulations.
