How are warning lights installed in different buildings?
Cranes are a difficult shape and they move around as well, most cranes work from top of the buildings and the cranes used are required to have warning lights. The Crane needs three warning lights, one on the fixed top and the other on the moving arm of the crane so it can be seen where it is going and how much space it is taking in the airway.
Light house Shape
The Lighthouse shaped buildings or towers are normally round, they need one on the top and others around the width in the circular form so that the shape can be visible from all sides and there is no part missing. The mid lights will be placed at the part that is above 150 meters and the top light will show how high the structure is.
Telephone towers have weird shapes but they follow essentially the same principle, the width of the area that reaches beyond 150 meters is covered in warning lights and the top parts have top lights. However, the structures that have extended arms on top have lights on those as well to indicate the width that the pilots need to avoid.
Multi-Sectional Buildings are the type that are tall but have weird shapes or basically have wings on the side of middle building that face different directions. The best way to create the Illusion is through the lights being placed in areas where the length and width of the building can show, however these buildings only have top lights and not middle lights because they are wider, rather than taller.
Rectangular straight tower
Tall buildings use Obstacle Lighting in a different manner than the wide buildings, these too need to have obstacle lights in the mid height on all sides before installing lights on the top on all sides too, this will show the exact shape of the building and help the air traffic navigate.
Telephone wires can be a hazard, not just for planes but also for helicopters and other smaller air traffic that comes and goes in the area. These usually have the tube like Obstacle lighting to help them stay lit. National Aircraft Warning Lights suggest that people understand the rules of the lights and the types before getting them installed.
