Aircraft warning lights for buildings, cranes, telecommunication towers
Obstruction lights for wind turbines, bridges, pylons, high voltage lines, and other obstacles
Aviation obstruction lights for ATC towers, airports, and helipads
S4GA offers a wide range of obstruction lighting such as aircraft warning lights for towers, aviation lights for airports and helipads, solar obstruction lights for off-grid obstacles located in remote areas. The following types of lights (ICAO) are available: high intensity obstruction lights type A/B, medium intensity obstruction lights type A, B, C; low intensity obstruction lights type A/B; solar obstruction lights type A (low intensity).
Certification of Aircraft Warning Lights
Our obstruction lights have been tested and certified by independent accredited laboratories. The certificates confirm compliance with ICAO, FAA, and EASA regulations, and are available on demand.

Depending on height and type of object that should be illuminated, ICAO (International Civil Aviation Organization) identifies few types of aviation lights. The main difference between them is in light intensity, color, and operating mode (steady or flashing).
| Light Intensity | Light Type | Color | Operating Mode | Minimum light output | Type of applications |
| Low Intensity | A | Red | Steady | 10 cd | Fixed obstacles |
| Low Intensity | B | Red | Steady | 32 cd | Fixed obstacles |
| Low Intensity | C | Yellow/blue | Flashing | 40 cd | Mobile obstacles |
| Low Intensity | D | Yellow | Flashing | 200 cd | ‘Follow me’ vehicles |
| Medium Intensity | A | White | Flashing | 2 000 cd | Obstacles with height over 45 m |
| Medium Intensity | B | Red | Flashing | 2 000 cd | Obstacles with height over 45 m |
| Medium Intensity | C | Red | Steady | 2 000 cd | Obstacles with height over 45 m |
| High Intensity | A | White | Flashing | 200 000 cd | Obstacles with height over 150 m |
| High Intensity | B | White | Flashing | 200 000 cd | Obstacles with height over 150 m |
