A light-signaling system comprising three lighting modules, in which: each lighting module comprises two projectors being fixed together; each projector of the lighting module comprising: an elongated cylindrical lens, the cylindrical shape of which is defined by a horizontal generatrix direction; and a linear light source parallel to the generatrix direction, extending over all or part of the length of the cylindrical lens in order to emit a luminous flux in the direction of the cylindrical lens; the cylindrical lens being capable of generating a main flat light beam (26, 27) by concentrating the luminous flux within a predefined elevation angular sector around the horizontal generatrix direction in the direction of the space located on the opposite side of the cylindrical lens with respect to the light source, and being capable of projecting the main flat light beam (26, 27) within a predefined elementary azimuthal angular sector around the vertical direction, the predefined elementary azimuthal angular sector being greater than or equal to 60°; each lighting module being configured to illuminate within an azimuthal angular sector smaller than or equal to the sum of the 2 elementary azimuthal angular sector(s) of each of the 2 projector(s); the bisectrix of the azimuthal angular sector of each lighting module defining a main direction of the lighting module, the lighting modules (281, 282, 283) being arranged such that the main directions (431, 432) of two adjacent lighting modules form between them an angle of 120°, such that the light signaling system is capable of emitting light around the light-signaling system in all azimuthal directions (Φ), in which two of the lighting modules, are defined as secondary modules and the third lighting module, is defined as the main module, each of the secondary modules is connected by a power supply cable to the main module, the main module itself being connected to a main power supply cable that is capable of being connected to an electrical power supply in order to supply the projectors of each lighting module (43, 44) with power, in which each lighting module comprises a housing fixing the two projectors together, in which the housing is horizontally substantially triangular in shape, two sides of the triangle each being defined respectively by the respective generatrix direction of one of the two projectors fixed to the housing and the third side being capable of being fixed to a support. each lighting module comprises two projectors being fixed together;
