NLC manual:

The Lopolight Navigation Light Controller (NLC) and Control panel, described in this document, is a simple system to install and operate, that can control several Lopolight navigation lights. It is delivered without setup, which must be completed as described in sections 5 and 6 before using the system.

The main screen is used for normal operation of the system. If any light groups are created, buttons for these will be displayed below the ship image. You can create light indicators, like green/red for sidelights and place the indicators in any requested position on the ship image.
