Most airports have some lighting for nighttime operations. The type and variety of lighting systems depend on the airport's capacity and complexity. Airport lighting serves as visual aids for nighttime and adverse weather approaches and landings, complementing radio navigation and landing systems. It provides visual indications and guidance signals for aircraft approaches and, during nighttime landings, integrates with radio navigation and landing systems to ensure aircraft visibility for landing under both day and night conditions.

The characteristics of an airport lighting system are determined by four main factors: configuration, color, light intensity, and effective range. Configuration refers to the positioning of each component of the system and the distance between lights; color is used to indicate different lighting systems within the airport, transmitting commands or information while enhancing visibility; light intensity is determined by the illuminance produced by light in the observer's eye—signals that are too weak may go unnoticed by pilots, while overly bright signals can cause dazzling effects, so the intensity must align with surrounding conditions. Effective range pertains to the various lighting systems in an airport. Due to differing functions and guidance modes, varying operational distances and lighting angles are required. Different airports, influenced by their respective levels, flight volumes, meteorological conditions, environmental differences, and navigation facility support, should exhibit certain variations in lighting configurations. Balancing cost savings with flight safety and harmonizing these elements with numerous airport factors remains an ongoing learning endeavor.
