Lights and lamps are essential elements of traffic safety, used primarily in the dark or in poor visibility conditions to make dangerous areas visible and to guide traffic safely. These include mobile lighting units such as warning lights that flash or rotate to indicate obstacles, as well as construction site spotlights that illuminate work areas over large areas. Illuminated traffic signs and reflective markings also play an important role by sending clear signals to road users. The targeted use of lights and lamps significantly increases road safety, prevents accidents and supports a smooth flow of traffic.
