Have you seen our ICAO LED Obstacle Warning Beacon available with or without InfraRed?

Have you seen our ICAO LED Obstacle Warning Beacon available with or without InfraRed?

This fantastic unit packs a punch! Complies with ICAO Annex 14 Chapter 6 regulations for low intensity Type-B, fixed obstacle lights. Units with the InfraRed option are also compliant with the IR requirements for low intensity obstruction lights outlined by the Finnish Transport and Communications Agency.

Measuring 135mm x 94mmm this IP66 rated enclosure has a 360° light output around the vertical axis, designed using LED’s that offer a high light intensity to ensure that the required brightness levels are met with as little maintenance required as possible by the end-user.

This beacon is perfectly suited to the outdoor environment with its carefully designed enclosure to minimise dust and dirt build up, is fully water tight and has an anti-tamper screw into a blind hole in the lens fitting.

What more could you ask for did you say? How about pre-moulded drillouts for M10 & M20 cable gland entries and long-life LED’s?! In particular using long life LED’s makes maintenance a thing of the past with this beacon, perfectly suited for those hard to reach areas where ICAO Obstruction Warning Beacons are required for!

Cranes & Safety Signals

Cranes & Safety Signals

Safety signals are essential when operating cranes, as they convey a message to nearby aircraft on passing through an area where a tall construction is located. The use of cranes can bring possible danger to any air flights. As a result, it is necessary to add warning signals on cranes to avoid any incidents.

Crane Safety Signals Explained

Erecting a crane is already a challenge in construction works. Today’s technology has helped to achieve a higher level of safety in the construction industry. There are so-called Obstruction Lights specially made for cranes, ready for installation in improving safety in all operations.

Obstruction Lights

An Obstruction Light is a safety signal on a crane that meets ICAO and FAA standards. Cranes are made visible at low light areas with the help of such a warning signal. It helps to avoid air collisions and other possible danger that involves cranes.

Not all cranes require the use of obstruction lights, except for cranes above 150-meters. The said level can bring troubles to air navigation, and so demands safety signals.

Obstruction lights come with various types, depending on the type of crane needing a warning signal, and its location. Determining such factors affects the number of lights to be installed on the crane.

There are the three types of obstruction warning light available for this particular application:

High-Intensity Red Colour Fixed Lights

These lights have 2000 candelas of minimum intensity, good for night use. Cranes measured 150-meters and above are to which high-intensity fixed lights were made. There must be a 50-meter gap in the installation setup. Add another set of lights in every 50-meter increased on the crane’s height.

Medium-Intensity Red Colour Fixed Lights

This is for cranes in between 90 to 150-meters in height. It must be visible at all angles when placed on top of a crane. The light will leave a mark for aircraft passing near the crane to be warned.

Low-Intensity Red Colour Fixed Lights

As its title says, these red colour fixed lights are for cranes below 90-meters and beyond 60-meters tall. It provides enough visibility in every direction for aircraft passing by.

Benefits of Crane Safety Signals

The use of beacons in the crane industry brings many advantages, not just for the business but also for surrounding traffic.


Crane safety signals are a good way to ensure safety when using cranes. There are audible signals available, however, most construction works prefer visual signals, as discussed above. Visual signals deliver more accurate warnings for people or vehicles passing by.

Final Remarks

As a conclusion, it is clear that warning beacons are of great importance in the crane industry in ensuring the safety of air navigation through safety signals.

The Role & Attributes of Aviation Signal Lighting

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.
