Leading lights for harbour approaches and navigation channels
Leading lights, also called range lights, define a leading line using a front and rear light at specified positions and elevations. Vikingegaarden supplies MSM MRL-M and MRL-D and Tideland Signal RLED-MasterRange and RLED-355, with installation, commissioning and support from Denmark.
Key features
A leading line is observed when the rear light appears vertically above the front light. Lateral displacement changes their apparent horizontal separation, providing a visual indication of position relative to the line.
The front and rear positions, elevations and separation are calculated from the approach length, channel width and observer heights. Beam divergence and alignment must provide the required coverage throughout the specified operating area.
MSM publishes maximum power consumption of 60 W for MRL-M and 10 W for MRL-D. The supply for each position is sized for the configured intensity, flash character and required autonomy; Tideland power data is confirmed for the selected configuration.
The supplied configuration is identified in the project documentation. Published figures and any applicable certificates are checked against the specified operating conditions.
Emiko monitoring is specified where supported by the equipment. Available signals, communications and alarm handling are confirmed before supply.
Commissioning records the installed equipment, settings and functional checks. The handover documentation defines the inspection and maintenance requirements.
Selection accounts for the mounting arrangement, exposure and access for servicing. Site data forms part of the agreed specification.

The project establishes the marking function, position and operating requirements.
Vikingegaarden confirms the equipment configuration and installation requirements.
The installation scope includes mounting, power and supported monitoring interfaces.
Commissioning verifies the specified functions and records the settings.
Models
Model selection is confirmed against the project requirements. The following values identify the published configuration data.
The MRL-M is an LED leading light for day and night operation. MSM publishes ranges up to 28 NM at night and 8 NM by day.
The MRL-D is an LED leading light with maximum power consumption of 10 W. MSM publishes ranges up to 24 NM at night and 5 NM by day.
The RLED-MasterRange uses panels with 2–15 LEDs according to the required output. Tideland Signal publishes ranges up to 26 NM at night and over 6 NM by day.
The RLED-355 is a leading lantern using the MasterRange II controller. Tideland Signal publishes range up to 24 NM, with spreader lenses available for beam selection.
Ecosystem
Vikingegaarden specifies, supplies, installs and commissions the equipment. Technical support and service are coordinated from Denmark.
The project specification records the equipment configuration, power supply, mounting and acceptance checks. Emiko monitoring is included where the selected equipment and interfaces support it.
Technical details
Nominal range uses atmospheric transmissivity T=0.74. Published maximum ranges require confirmation for colour and configuration; day range is a separate performance figure.
