Safe Sign‘s photoluminescence Low Location Lighting systems are intended to guide people to safety in the event of an emergency. The LLL (Low Location Lighting System, often referred to as a Escape Route System, allows evacuation routes to remain illuminated under conditions as of power failure. Fire fighting equipment is identified at floor level as a result of the LLL mini symbols placed on the system. The LLL system is showing a clear “means of escape” message which will lead the personnel and passengers to an assembly station and from there to a safe place. To trust this system, you need to be sure it works every time. You don’t want to be unsure wether you chosen the right LLL system for your vessel or not. You want to have a system with great performance at the same that it is looking premium and is environmentally friendly. When looking for the best solution, you should choose LIGHT LINE XXL, The New Generation of Photoluminescent Low Location Lighting Systems. We produce, sell and install Low Location Light systems in accordance to IMO RESOLUTION A.752(18) and ISO 15370:2021. The turnkey service includes: mapping, planning and professional installation services.

The photoluminescence LLL system gives you a guiding safety system that you can trust, in any environment and situation. The only thing this system needs is light. When the “glow-in-the-dark” LLL system is exposed to light, be it natural light or light from fixtures, it charges itself. This is how that system always works.

LightLine Low Location Light System

Implementation of Low Location Lighting System, LightLine Signwell

The LightLine LLL System is the easiest and most cost-effective Low Location lighting system to install, requiring only the attachment of LLL strips where necessary. You can easily cut the necessary lengths with a knife. The system is completed by placing LLL signs/stickers in the right places. When you decide to install our LightLine system, you can save time up to 200%.

LightLine Pet-X photoluminescence strips are PVC/halogen-free plastic strips with backlight material and strong self-adhesive foam tape on the back. The material has a “shiny” surface that is easy to clean and at the same time gives it a high-quality appearance. LightLine tapes are available with 5 mm safety green edges at the top and bottom of the tape.

The standard length of the LightLine-LLL-System is 99 cm, height 50 mm, thickness 1.5 mm and they are manufactured with high luminescence class XXL. All LightLine-LLL tapes have a self-adhesive backing that is easy to attach during new shipbuilding or renovation projects. LightLine-LLL tapes exceed all current requirements. On request, we can manufacture LightLine strips with other widths and/or other coloured marking stripes.


This LLL system is easier to install, more cost-effective, lighter and overall only requiring the application of the LLL strips where needed. This without drilling or “destroying” the wall with other forms of glue. This saves a lot of extra weight when not needed any aluminium profiles.

Furthermore the durability of our PL LLL system is that it does not shiver and make noises from getting loose from the wall after a couple of years as LLL systems with profiles can do after some time from vibrations caused from the ships engines and sea. Easier replacement, since it is attached directly onto the wall and only stretching out 1,5mm. It will last intact for a much longer time and if needed, it is easy to remove one small damaged section and replace with a new strip. This instead of having to remove the whole aluminium profile that can be at longer corridors even up to 3 meter long, which makes the replacement work more expensive and time consuming

LightLine LLL -Old generation profile system

LightLine LLL -profile system consists of pressed aluminum rails and rigid photoluminescence LLL tapes. Our selection includes two different types of profiles; corner or flat profile with 55.4 mm wide visible backlight strip. The performance of rigid LLL panels is certified by DNV. The flat profile is made of anodised aluminum and contains a central channel in which photoluminescence LLL material is placed. End pieces are available to protect the ends of the profile. The corner profile is slightly angled away from the vertical so that the photoluminescence strip receives more light.


Signwell is certified to carry out LLL measurements. We also do inspections of the overall escape route system and report the effectiveness and accuracy of the current exit routes and safety signage system, to ensure that they are fully compliant with regulations and requirements. If you want more information about the sign inspection, contact us today and get started.

In the maritime industry, it is mandatory (IMO RESOLUTION A.752(18)) to renew LLL systems certificates every 5 years. This periodic measurement must be in accordance with IMO/SOLAS regulations and certified by the classification societies. We offer DNV-approved periodical measurement and certificate re-approval for your vessel, for backlighting and electronic LED LLL systems.
