Solar Obstruction Lights For Transmission Towers

By:Avlite Systems | June 21, 2016
Application: Permanent ICAO LIOL Type A fixtures for 132 kV electricity transmission towers
Location: Middle East
Site: Undisclosed


The customer required an ICAO compliant night time warning light system for transmission towers across the Middle East. The system needed to be low-cost, quick and easy to install and completely self-contained with an integrated power supply and fully automated to enable the lights to activate at dusk and deactivate at dawn.

A low-maintenance lighting system was also needed that wouldn’t require constant repairs or component replacement and that would run reliably for many years with minimal operator

intervention. If maintenance was required, however, the light fixtures or their components needed to be easily replaced without interrupting or effecting the tower’s operation or the performance of the lights on other towers close by.


The solution:

Avlite’s authorised distributor for the Middle East, recommended Avlite’s ICAO compliant solar- powered obstruction lighting solution to the customer as it met with their requirements.

To comply with ICAO standards, Avlite’s AV-C310 is independently tested to meet the photometric requirements set out by ICAO for lighting towers up to 45 meters.

The customer selected Avlite’s AV-C310 ICAO LIOL Type A fixture after a successful 2-year product trial, many in-country visits – including product familiarisation and training hosted by Avlite’s manufacturing facility in Australia.

The AV-C310 is fit-for-purpose, straight from the box and factory set to its steady-on, dusk-till-dawn operation mode allowing for efficient installation. The local installation crew needed only to activate the lights (prior to installation) by connecting the 4Pin battery connector inside the unit and securing the light head with just four bolts. The completely self-contained fixture – weighing only 9.1kg – was then hoisted up and fixed to the apex of each tower and quickly and easily bolted into position by two crewmen. Once bolted on, the lights were fully operational.

The project ran without complication with an impressive 18 lights installed per day.

What Our Client's Say

“It is a great benefit to our community to have this [Avlite’s helipad lighting system] installed and commissioned at CareFlight’s Toowoomba base. Avlite’s particular type of lighting lends itself to a lot of applications given that it’s easy to install, doesn’t require electricity as its solar powered and can be remotely controlled. It’s a fabulous technology, obviously a world leading technology and from my point of view, it’s great to see an Australian Manufacturing success story.“

-Cr Mike Williams

“For an aerodrome operator to provide equivalent night-use runway standards for the RFDS and other fixed-base users at around one-third of the cost of a traditional mains-powered runway and taxiway lighting system, there has to be greater recognised merit for this (solar-powered) alternative especially in a location like ours where it is sunny most days of the year.”

-Jenny Kox

“Our industry appreciates the on-going support of this Australian owned and operated company whose solar powered airfield and helipad lighting systems assist in the improvement of safety for both fixed and rotary wing aeromedical flight crews and passengers around the country.”

-Graeme Field

“As the busiest Helicopter Emergency Medical Service (HEMS) based in the State [of Queensland], the benefits [of Avlite’s helipad lighting] are many. Not only does it [the system] enhance the safety of our operations, it also helps us to continue to improve our level of service delivery to the community and to our customers.“

-Ashley van de Velde

“These lights [AV-70s] have been a great asset to many outback communities that previously we were not able to access 24/7.”

-Alan Benn

“Just to let you know the new airport floodlight has now been installed for several weeks and the medical staff and Power and Water staff [who look after the airport] agree it has made things much easier and safer for night-time medivacs. Your assistance with enabling us to have this basic but important infrastructure is much appreciated.”

-Stephanie Fielder

“Since starting our distributorship with Avlite, we have gone from strength to strength with the great range of solar products and of course the fantastic support of the Avlite staff. It’s been a good year for us. May it continue.”

-Eddie Lacina

“Re: Avlite AV70 taxiway lights, are working really well. Thank you for your assistance in getting our ramp up and running.”

-Capt. US Air Force

“[In reference to more than 2,000 AV70 taxiway lights installed] Those Taxiway lights work great, we are not having any problems with those AV70’s. Thanks a lot.”


“The lights are installed and are operating beautifully.”

-Strathcona Airport

“[In reference to Avlite radio controlled obstruction lighting] They are really neat to watch come on, they come on instantly and are a great addition to our pilot training school. The lights are currently set on medium intensity as high intensity is very bright.”

-Airport Stafft

“We did install all of the lights. We even used a few red lights as obstruction markers on top of 68 meter power line towers. I finally found a high quality camera and took some photos. I will send them to you as soon as I can download them. We submitted some additional light orders to our contracting office, so you can expect to receive a bit solicitation from them soon. The lights are working great and we appreciate the support.”


“[In reference to a visit to the Avlite production facilities] On arrival at Avlite I was greeted by sales manager Sharon Bedson, and was treated like a VIP. I was given a tour of the production line and had a close look, and an in-depth explanation of all the components of the Avlite system. The staff were fantastic and very helpful. It was truly fascinating and I now have a good story to tell Wanarn community members on my return. I was also shown the vast range of solar system lights and other products that they make.
I have recommended Avlite solar lighting systems to many local communities and Avlite will be my first stop shop if the community needs anything regarding solar power in the future. Well done, and thank you Avlite.”
