Aviation Light Signals

Aviation lighting is essential in keeping everyone safe; it ensures that building and objects can be seen in low light as well as helping both the pilot and air traffic controller communicate on landing in the form of light signals. In case of communication failure or when an aircraft isn’t equipped with a radio, light signals are used using a signal lamp. Signal lamps have focused bright beams that can generate red, white and green lights which can be steady or flashing. Each of these colours and patterns are instructions for aircraft pilots and have a specific meaning, depending whether the aircraft is in flight or on the ground. The aircraft pilot must recognize both the colour and pattern (steady or flashing) to properly decode the message from the control tower. Aircraft pilots can acknowledge these instructions by rocking the aircraft wings, moving the ailerons, or by flashing their navigation lights.


Aviation Light Signal Colours and their meanings

Just like a traffic light, aviation light signals use three different colours. However, instead of red, green and amber, used by road traffic signals, the Air Traffic Control light signals use the colours red, green and white. As mentioned above, each of these colours have a specific meaning and vary depending whether the aircraft is in flight or on the ground.

Aviation Light Signals on the Ground

Steady Green Light – The steady green light signal on the ground means the aircraft is cleared for takeoff and the pilot may proceed for takeoff.

Flashing Green – The flashing green light signal on the ground means that the aircraft is cleared or authorized to taxi.

Steady Red – The steady red light means the aircraft must stop immediately and hold their position.

Flashing Red –The flashing red light means the aircraft must taxi clear of the runway in use or get off the runway. The air traffic controller wants the aircraft pilot to find the nearest taxiway and get off the runway to allow other aircraft to use the runway.

Flashing White – The flashing white signal means the aircraft pilot must return to their starting point. The air traffic controller wants the pilot to return to the airport parking apron.

Alternating Red/Green – In countries such as the United States, the alternating red/green signal light means an important warning to the aircraft pilot to exercise extreme caution.

Aviation Light Signals in the Air

Steady Green – Green signal lights always indicate a GO. This means the aircraft is cleared to land.

Flashing Green – The flashing green light signal to an aircraft in flight means the aircraft should return for landing and is essentially a Go-Around command. The aircraft do not have a clearance to land, so the aircraft must return for landing via Go-Around.

Steady Red – Red light signals always indicate a stop command. However, an aircraft in flight is impossible to stop. So red light signal for an aircraft in flight means, the aircraft must continue circling and give way to other aircraft until the air traffic controller indicates that you are cleared to land by giving a steady green light.

Flashing Red – A Flashing Red light signal to an aircraft in flight indicates danger, the airport is unsafe and do not land.

Alternating Red/Green –Alternating Red/Green light signal applies to both aircraft on the ground and in flight. It indicates the aircraft pilot to exercise extreme caution.

Light signals are rarely used today by aircraft pilots because of the presence of radio for communication. However, radios are not always reliable and sometimes stop working. In times of communication failure, this will come in handy and is really important for aircraft navigation. An aircraft pilot will have the need to fall back on Aviation Light Signals for communication in order to avoid accident and ensure safety.

Communication is also key between the pilot and obstacles along his flight path – such as high buildings, masts, towers etc. To alert the pilot to the danger of these, warning beacon lamps are added to tall objects. The use of such lighting is intended to reduce hazards to aircraft by indicating the presence of obstacles.

The presence of objects which must be lighted, should be indicated by low, medium or high intensity obstacle warning light, or a combination of such lights.

Fixed obstacles of 45m or less in height, width and length are normally lit by a single, steady, red light, placed at the highest practicable point. Obstacles of greater size are normally provided with additional red lights in order to outline the extent of the building.

Air flight paths at night must be more visible to reduce potential collisions. Beacon lights help to provide a warning light to airborne aircraft – for this application they are available in either red or white for increased visibility.

FAA/ICAO Lighting Requirements

Lighting for this purpose should conform with FAA and ICAO lighting requirements, to ensure continued safety. Aviation warning lights are often installed in pairs, with the first pair placed on top of the fuselage and the other at the bottom. They are usually a static (non-flashing) light, which lights red in colour, providing a recognized signal within the aviation industry.

Three Purposes of Beacon Lights in Aviation

Several aircraft types rely on the purpose of beacons in every flight. Safety is priority, and these lights have become a necessity.

1. They enhance aircraft visibility

Since planes or helicopters are not very often visible from the ground, installing beacon lights on them is necessary. This prevents any collision problems between aircraft in flight or traffic below.

2. To improve pilot visibility

Warning lights are not only essential for the safety of aircraft, but more so for peoples welfare. Pilots must be properly notified through the flight deck windows, therefore specific lighting is necessary for a safer flight, such as:

• Landing Lights

• Runway Turnoff Lights

• Taxi Lights

• Wing Inspection Lights

• Ice Detection Probe Lights.

These lighting systems help the pilot to perform a safer flight for all.

3. To warn of tall buildings or infrastructures

It is extremely important that aircraft are aware of any tall buildings, or even temporary structures, such as cranes, to avoid any chance of collision. Whilst there is a variety of different options available, it is vital to ensure these devices meet ICAO requirements, as high visibility is essential. Other lighting devices used in aeronautics are navigation lights and strobe lights. But, in this instance, aviation warning lights are used far afield in a variety of different industries.

Final Words

To sum it up, aviation warning beacons keep aeronautic activities a lot safer, when constructing large buildings it is vital that these warning lights are taken into serious consideration.

The Role & Attributes of Aviation Signal Lighting

Click here for more information.

Aviation signal lights are of extreme importance, to ensure the safety of passengers, pilots, as well as cargo. Through the increasing use of LEDs or light-emitting diodes, lighting technologies have shown great improvement, whereas in the latter years, less efficient and unreliable incandescent lamps were utilized.

Some of the attributes that aviation signal lights today improve include their colour, life, and electrical characteristics.

Aviation Signal Lighting And Its Role

Aviation signal lighting, or aircraft warning lights, are characterised as high-intensity illuminating devices that are mounted to tall structures. These devices work as a collision avoidance measure, allowing possible accidents causing structures to be visible for pilots.

Aviation signal lightings are usually used at night time, but they can also be used during the day. In order to provide visibility over tall structures in a dark environment, these devices need to have sufficient brightness, as well as being visible from afar in all directions of the structure.


In order to alert other aircraft of their proximity, aircraft employ collision avoidance lighting systems. These signalling lights include landing lights, flashing beacons in red or white colour, wingtip navigation lights, and wingtip strobes.

A red light on the left wingtip and a green light on the right wingtip are required for the wingtip navigation lights. Landing lights are used during descent and landing approach, and on other occasions, if the flight crew or operator finds it appropriate.

Aircraft warning lights or aviation signal lighting comes with heavy responsibility in terms of aviation safety. For this reason, they have to be mounted carefully and properly to benefit from the visibility they provide.

These safety measure devices must be capable of providing sufficient lighting to be effective, not only at night time. Low light conditions can also happen during the day, such as cloudy weather conditions, which also requires aircraft to use aviation signal lighting.

Mounting Aviation Signal Lights

Generally, such lights can be seen connected to an elevated structure such as broadcast masts and towers, electricity pylons, high elevation water tanks, high buildings, chimneys, cranes and wind turbines. Lighting may also be needed for smaller structures located near airports; an example of this is the 2013 constructed south scoreboard at Lambeau Field in Green Bay, Wisconsin. It is the highest structure in the nearby Austin Straubel International Airport’s general area.

The ICAO or International Civil Aviation Organization sets the standards for the reliability and characteristics of aviation warning lights. These standards are generally adopted worldwide.

Lights are typically positioned at different heights on the tower in groups of two or more around the building. There will often be set at the end, and then one or more sets spaced up the structure equally. The Belmont Transmitting Station in Lincolnshire has nine clusters of red lights evenly spaced along with the mast’s full height.

Final Say

Aviation signal lighting plays an important role in terms of keeping all passengers, pilots, and cargo of an aircraft safe and secure during flights. Aside from that, it also provides better visibility on tall structures to prevent a collision.

A Guide on Crane Warning Devices


Warning devices for cranes are essential, due to their tall construction. They give a message to people nearby, those who are passing beneath the crane, and also to nearby aircraft.

Speed up Construction

The erection of sturdy high-rise structures has never been easy, as it requires a lot of manpower, time, and effort. In such a case, the use of a crane is sought. Cranes have necessary functions that assist the construction industry hugely, and have indeed become a necessity. They can lift heavy objects and move them anywhere in an instant, which can help in saving time, strength, and effort of the workers. It can also ensure their safety. However, as with any tall structures or machines, there is a possible danger that it can cause, especially to airborne traffic.

Obstruction Lights

Obstruction lights are installed to cranes to make them visible even at night. They give a signal or a warning to aircraft not to meet a possible danger. They can also help avoid collisions with other cranes or structures.

Obstruction Lights According to your Needs

The type of crane and its height are considered when choosing the correct obstruction lights. The height considers the type of obstruction light, and the type will be the basis of the number of lights to be installed. The standard level is 150 meters. If a crane is below the said level, an obstruction light is required only if its location can be a danger to air navigation. On the other hand, an obstruction light must be installed to a crane taller than 150 meters.

Red Colour Fixed Lights. These lights are installed for night use. They show a red steady burning light with a minimum intensity of 2000 candelas. For cranes that are 150 meters tall and above, they are installed close to the top and placed with at least a 50 meters gap in between. For every additional 50 meters on the crane’s height, an additional number of light must be installed.

Medium Intensity Red Colour Fixed Lights. The light on the top of a crane with a height between 90 to 150 meters indicates its height. The other lights on the crane’s jib mark its distance. These lights should be visible at every angle.

Low-Intensity Fixed Red Lights. These are used for cranes and tower cranes between 60 to 90 meters. They are usually installed on top of the crane to ensure visibility. These lights should also be visible in every direction.

Things To Remember

Assessing the case and condition of a site is necessary to put up a crane that would be effective in use. It is also essential to consider the standards in design and installation of the obstruction lights on the crane, taking into consideration the number of obstruction lights to use, their visibility, and positions. It is also necessary to ensure that it meets the regulations of ICAO (International Civil Aviation Organization) and FAA (Federal Aviation Administration). This is not only to operate peacefully but also to ensure safety.

Thanks to our technology nowadays, obstruction lights have improved tremendously. Now, they don’t only function as a warning or signal to avoid collisions or danger, they have become so advanced that even just a possible danger can already be detected. As a result, there is a higher level of safety precaution.
