1. A distress signal system for sea vessels comprising two or more navigation lights, which are interconnected in an electrical circuit and arranged to emit a steady light in different directions in an operating state, characterized in that the system further comprises:
a control means connected to the electrical circuit, which control means is arranged to vary the current to the navigation lights in a distress signal state in order to vary the light emission therefrom according to a pre-programmed pattern for formation of a well-established distress signal;
a manually actuatable actuator comprising a switch connected to the control means for activating or switching off the distress signal state by activating or switching off the control means; and
a light activating means coupled to the electrical circuit, which light activating means is arranged to provide, when activated, a power supply of said varying current to said navigation light, in connection with activation of the distress condition, regardless of whether said navigation light is in operating state or not; wherein
the electrical circuit comprises at least two circuits, the at least two circuits being connected in parallel, wherein each of the at least two circuits is connected to a power source via an electrical switch, and wherein the light activating means is connected to the power source and each of the at least two circuits and is arranged to electrically bypass each electrical switch.
