The invention relates to a light signal, more particularly for rail-bound traffic routes, comprising a light source (10) and an optical system for signal aspect visualization, more particularly into a far range and a near range angled relative thereto. In order to achieve a reduction of phantom light that suffices to be able to dispense with a shield, provision is made for the optical system to comprise a Fresnel lens (13), the light entrance surface of which has Fresnel structures (15) and the light exit surface (16) of which is designed in such a way that every tangent (17) to the light exit surface (16) is at an angle of ≥ 105° relative to an optical axis (14) of the optical system.
