Abstract
A distress signal system for a sea vessel comprises several navigation lights (11, 12, 13, 14, 15), which are connected in an electrical circuit and arranged to emit a steady light in different directions in a normal operating state. The distress signal system comprises a control means (28, 30) connected to the electrical circuit which in a distress signal state is arranged to vary the current to the navigation lights (11, 12, 13, 14, 15) in order to vary the light emission therefrom in accordance with a distress signal, such as SOS. A manually actuatable actuator (24) is connected to the control means (28, 30) to activate or deactivate the distress signal state. A light activating means (26) is arranged to provide a varied power supply to the navigation lights (11, 12, 13, 14, 15) in connection with activating the distress state, regardless of whether these are in operating state or not. Such a distress signal system can be provided by connecting a separate distress signal unit comprising a control means to the navigation lights of a sea vessel.
