In harbor safety and security, lighting plays a crucial role by enhancing visibility for navigation, reducing risks of accidents, and deterring unauthorized activities. Proper lighting illuminates critical areas, including docks, piers, and entry points, aiding vessel identification and assisting with surveillance. It supports harbor operations at night, improves response times for emergency services, and reduces hazards. Security lighting also discourages intrusions and theft, while ensuring safe, regulated access to port facilities.
