LED Low Location Light SYSTEM

The LED LLL system is designed for exit routes. Its principle is the same as the LLL backlight system, but this product does not need a light source to glow, and its glow does not fade over time. Due to its good flexibility, the installation can be done, for example, on curved walls. We produce, sell and install Low Location Light systems in accordance to IMO RESOLUTION A.752(18) and ISO 15370. The turnkey service includes: mapping, planning and installation.

How does the LED LLL System work?

The LS Low Location Lighting (3L) System is a completely independent system consisting of LED control lines called in endless configuration, from LED signs that can be integrated into the system. A variety of aluminum profiles for all installation purposes and power supplies with or without battery backup capable of feeding more than 1,000 m of 3L LED strip and our system is compatible with the most common installed 3L systems.


According to the regulations, ships carrying more than 12 passengers must have a low position lightning system installed. The light-illuminating LLL system charges the ship’s lighting and uses the energy it collects to illuminate in the dark.

Together with our team, we can inspect, measure and report on your current exit routes and safety guidance system to ensure that they are fully compliant with regulations and requirements.

In the maritime industry, it is mandatory to renew the certificates of LLL systems every 5 years. This periodic measurement shall be in accordance with IMO / SOLAS regulations and certified by the classification societies. We provide DNV GL-approved periodic measurements and re-approvals for your vessel, backlighting and electronic LLL systems.

Signwell is a DNV certified LLL inspector.
