PROBLEM TO BE SOLVED: To properly control lighting of facets in a light guide, so that a beam emitted from a lighting module can form a desired shape by positioning the light guide precisely. SOLUTION: A light guide 1100 is equipped with a set of transparent strips 1110, 1120, 1130 which are piled up together. A light module 1000 includes a reference member 1200 equipped with first parts 1210, 1220 forming a horizontal reference plane and a second part 1230 forming a vertical reference plane. The piled-up transparent strips abuts to the two groups of parts of the reference member 1200 in predetermined positions on a longitudinal axis of the light guide 1100, and facets 1111, 1121, (1122, 1131) of the light guide 1100 cooperate with lenses 1111a, 1121a, 1122a, 1131a so as to project optical images corresponding to the facets in the light-emitting direction E. |
