Remotely Monitored Bridge Lights

By:Sealite | February 24, 2017
Application: Bridge Lighting with GSM Monitoring
Products: SL-BR (green and red), GSM Monitoring
Location: Tar Heel, North Carolina USA


North Carolina is a state with vast topographical challenges. It boasts a landscape that extends from sea level to mountainous (the Appalachian Mountains, containing the highest point in North America east of the Mississippi). Due to the varied landscape, weather conditions can change frequently and severe weather incidents are common. Such conditions make operations, maintenance and installation of infrastructure time-consuming, expensive, and difficult. Various levels of equipment and manpower are necessary to reach, repair or maintain such infrastructure, depending on locale.


The NC DOT expends significant funds dispatching crews to remote locations to monitor the operation of bridge lighting. As the new Tar Heel Bridge was being built (replacing the prior bridge), the NC DOT was looking for lighting alternatives. They required lighting that did not require the installation of expensive electrical cabling and conduit. They also sought remote operation and monitoring to limit on-site operational status checks, necessary following severe weather incidents.


The installation of Sealite’s solar-powered SL-BR Bridge Lights removed the need to run electrical conduit, making for an easier installation. GSM monitoring allowed the NCDOT to remotely monitor light operating conditions from their offices, approximately two hours away. Diagnostics such as lantern status, battery condition and GPS positioning are sent via email, text, or viewed on Sealite’s secure web portal, providing current light status reports. Once installed, no special vehicular equipment was needed to reach the lights for status checks, saving the NCDOT additional costs in both labor and operation.

What Our Client's Say

On behalf of Karachi Port I am pleased to acknowledge your good service and provision of the new SL-75 solar marine lanterns installed by your firm in the harbour channel at Karachi Port. The new lanterns are very feasible and useful and equipped with the latest navigational technology.

[Re: Sealite SL-LED Lightsource at LaCorbiere Lighthouse], We were impressed with Sealite’s solution which provided a modern, reliable and efficient light source whilst remaining sympathetic to the lighthouse’s heritage and significance as a local landmark, but most importantly to improve upon reliability and to continue its vital role in aiding the safety of navigation in Jersey’s waters, as it has done for nearly 130 years.

As one of your new distributors (Belize and Honduras, Waller Marine Belize LTD), I would like to express my congratulations to you and your people in providing reliable, dependable and inexpensive products. Formerly we were distributors for a Canadian made product but these were found to be too expensive for the market and also offered only difficult and complicated programming. Our first order of lights from you (SL15’s) took only four days to arrive from Aussie Land, when I opened the box they were still flashing. I tested a SL60 (white) for four days (steady on) before it required a recharge…remarkable. I will be placing another order shortly. Keep up the good work.

[Re: Installation of WindTalker for kite-surfing club], The WindTalker™ is a big success here in Cyprus, thanks to your after sales support the unit is now functioning perfectly.

We choose to sell Sealite … this is a long story, well we treat Sealite as our own and the relationship we have developed with Jeff and Chris and their attitude and commitment towards growing Sealite to this stage is remarkable. We feel at home when talking to them and the staff of Sealite and this in turn gives us more security and strength in selling products in India.

[Re: Sealite Solar-Powered LED Area Lighting system], We chose the Sealite system for the Jacobs Well Queuing Pontoon due to our previous experience with Sealite’s product, its durability and construction.

-Peter Taylor

I just wanted to say thank you for the light and bracket Sealite supplied to Birkenhead Marina. As the other lights (old ones) need new batteries I will be replacing them with new lights from Sealite and the same brackets that you supplied with the light we received last week … Your product is excellent and the system of setting the light is good also. Thanks again for all your trouble.
