A tall telecommunication tower requires multiple levels of obstruction lighting, depending on its tower height. Generally, the one at the top is usually a medium intensity Mi-2KP and a few units of low intensity Li-3272 at the intermediate level subject to how many tower legs it has. AC or DC-powered types are generally recommended, however solar-powered types can also be used as an alternative.
Pylon, also known as a high voltage transmission tower requires obstruction lights and warning spheres as it poses great hazard to aircraft. Normally it requires medium intensity solar MS-2KP at the top and low intensity solar at the arm as suitable power supply is not available on the structure.
Building are also considered an obstacle that requires obstruction lighting, subject to its height and blocks. Higher buildings may require higher brightness type of obstruction light and multiple levels of lighting. Intermediate levels of lighting are required to be installed at the edge of the building.
Wind turbine is an obstacle that poses a great hazard requiring obstruction light to be installed at its nacelle. In the case of a wind farm which consists of a few numbers and a group of wind turbines, GPS synchronisation system may be required to ensure all the lighting has synchronised flashing.
Skyscrapers like Petronas Twin Tower require the highest brightness of obstruction light in the category which is the high intensity type A aviation light, and may require multiple levels of lighting.
Industrial chimney, boiler, flare stack and other structures alike are required to be marked by the obstruction light. It may require single level or multilevel lighting. Due to its diameter and location of installation below the fume exit, it is required to install more than a unit of obstruction light around its structure to ensure the 360 horizontal light beam.
Factory, hanger and warehouse type of building that has greater width and length compared to its height. They are normally designed with height less than 45 m (150 ft) and would require low intensity Li-3272 or Li-3201 aviation lights. It may require a few numbers of light as its longitudinal distance between each low intensity shouldn’t be more than 45 m (150 ft) intervals, based on the ICAO standard.
