Skyscrapers

 

Industrial chimneys

 

Bridge supports

 

These installations prevent collisions by marking potential hazards to air navigation.

 

2. Airport Perimeter and Runway Lighting

Modern airports increasingly adopt ICAO LED solutions for:

 

Runway edge lights

 

Taxiway guidance systems

 

Approach lighting arrays

 

Visual glideslope indicators

 

3. Helicopter Landing Zone Marking

Helipads and hospital landing zones utilize specialized ICAO LED configurations to ensure safe operations during night and low-visibility conditions.

 

Technical Specifications of ICAO LED Systems

ICAO Annex 14 Volume I provides detailed technical requirements for LED aviation lighting:

 

Light intensity classifications (low, medium, high)

 

Color specifications (red, white, or dual-color systems)
