These performance standards apply to Navigation Lights
(NLs), Navigation Light Controllers (NLCs) and associated equipment
to be fitted onboard vessels in accordance with COLREGs.
These equipment should be designed, tested, installed and maintained
based on these standards, taking into account that the purpose of
Navigation Lights is to identify ships and to notify their intentions
at sea and that the purpose of a Navigation Lights Controller is to
provide means of control and monitoring of the status of navigation
lights onboard the vessel to the Officer of the Watch (OOW).
