Abstract
A signal lamp comprises at least one light source arranged at the entry of a longitudinal light guide oriented with its longitudinal axis (γ) in the direction (s) of light exit from the lamp, and at least a portion of the light from the light source passes into a transversal light guide oriented with its longitudinal axis (α, β) transversally to longitudinal axis (γ). Transversal light guide is fitted on a part of its casing with an exit surface for light to exit from the lamp. Longitudinal light guide is fitted with at least two reflective surfaces that do not overlap when viewed in the direction of longitudinal axis (γ), and that are inclined towards axis (γ) to reflect light beams to at least two transversal light guides having their entries against the reflective surfaces, and their exit surfaces at a distance from each other in direction (s).
