TYPICAL OBSTRUCTION LIGHTING FOR TELECOM/BROADCAST TOWERS, LATTICE AND STEEL TOWERS
These recommendations are based on Chapter 6 of Annex 14 of ICAO (International Civil Aviation Organization latest edition) and are given for information only
Red obstruction light for night marking
For telecom towers below 45 meters high:
• 1 or 2 red fixed low intensity at the top.
For radio or telecom towers between 45m and 105m high:
• 1 red flashing medium intensity type B at the top.
• 2 or 3 red fixed low intensity type B at mid level (not more than 52 meters from top or ground level) If the tower is higher than 105 meters, additional levels of red medium intensity and low intensity lights should be added alternatively.
At the bottom photocell and control cabinet in option (built-in photocell inside the flash-head can also be used)
• For towers 105m to 150m high, 2 to 4 white flashing medium intensity type A at intermediate level.
• For towers above 150 meters high in case of presence of red and white painted strips, additional levels of medium intensity type A every 105 meters max (high intensity in other case).
