Aircraft warning lights refer to high-intensity lighting devices that are attached on structures such as buildings in order to avoid collision. These devices serve as a measure for avoiding collision. The intention of using these devices is to make buildings more visible to aircraft passing by. In most cases, they are used at night even though they can be used during daytime too. Aircraft warning lights on buildings must be visible from several miles away for them to be effective.
In general, there are two types of these lights in use today, that is, red and white lamps. The red lamps may be constantly on or they may turn on and off at a slow rate. The rate is usually predetermined and does not accelerate or slow down. White varieties are usually xenon discharge flashers. In most countries such as the UK, white flashers are being replaced, with red ones being adopted more.
Red lamps have incandescent filament bulbs installed into them. Red lamps have a very short lifespan, something that has made their design to be ruggedized to improve lifespan. Operating power used in them is also lowered in order to achieve a higher lifespan. Incandescent bulbs are in the recent past started to be replaced by high-power red LEDs.
The lifespan of LED-based lamps is much longer. The long lifespan raises reliability while reducing maintenance costs. Xenon flashers are actively being replaced by some manufacturers who are introducing medium-intensity strobes that are based on LED technology. As such, the desirability of white flashers in the US is still high. Most structures have white flashers during daytime and red lamps during nighttime.
Red lamps tend to be in common use in urban and populated areas. This is because pilots can spot them more easily from great heights. Even though not as common as red lamps, white flashers are also used in urban areas. White flashers are not preferred to use in urban areas because they match with background lights so that they cannot be spotted easily. In rural areas where background lights is not a problem, they are in common use.
These warning lights can be placed on any tall structure in general. Some of the structures they are commonly attached to include water tanks, electricity pylons, broadcast towers and masts, tall buildings, wind turbines, chimneys, and cranes. If the structure is shorter, but located near an airport or airstrip, these lamps may still be attached to them to serve as warning to aircraft that is trying to land on the field.
Normally, the lights are arranged in clusters of two or several lamps around the structure. The arrangement is done at specified heights along the height. In most cases, a set will be placed at the top of the structure followed by several sets at specific intervals down the structure. How many sets are installed will be determined by the height of the structure.
Major concern related to these lamps is that they contribute to light trespassing. Most people located in places with the lamps usually complain of light trespass. Light pollution has also been reported together with towerkill of birds.
