Alarm and light warning systems for on- and off-highway applications
Alarm and light warning systems are safety devices widely used on and off highways. On the highway, these systems are often used to warn drivers to stay away from road obstacles, such as road works, traffic accidents, and jams. For example, on highways, traffic authorities often use variable information signs (VMS) to warn drivers of traffic situations.
In off-highway applications, these systems can be used to warn workers, drivers, and pedestrians of the need for safety when moving around hazardous areas. For example, in rock and mineral extraction sites such as quarries, mines and construction sites, alarm and light warning systems can be used to alert drivers and workers to avoid hazards such as collapse and collapse. In addition, in the operation of large machinery such as vehicles and trucks, these systems can help drivers avoid obstacles and reduce the occurrence of accidents. In summary, alarm and light warning systems are important for on- and off-highway applications to improve safety in a variety of locations.
