Signalling lights, often associated with industrial safety and automation, are products used across various sectors including manufacturing, transportation, and emergency services. While not a specific brand, signalling lights are a category of devices produced by multiple companies worldwide. For instance, companies like Patlite Corporation (Japan) and Federal Signal Corporation (USA) are prominent manufacturers. These lights serve as visual indicators for warnings, status alerts, or operational signals in machinery, vehicles, and public safety systems. Common products include LED beacon lights, strobe lights, and traffic signals, designed for high visibility and durability in harsh environments.
