Abstract: The optical system comprises at least one pair of adjacent light-guides (1a, 1b) of a longitudinal shape the surface of which comprises a shell (8) that connects two ends (6) of a light-guide (1a, 1b), and at least one pair of light sources (3), associated with the ends (6) of the light guides (1a, 1b) at the same side of the light guides (1a, 1b), to emit light rays (10) and to ensure their propagation in the direction from the end (6) of the light-guide (1a, 1b) further into the light-guide (1a, 1b) body. Either of the pair of the light-guides (1a, 1b) is equipped in its rear part with optical elements (2) to reflect light rays (10) to its longitudinal exit surface (7a) located on the shell (8) for their exit from the light-guide (1a,1b).

Abstract: The light device for a vehicle comprises an optical module comprising a reflector (2), common for signal light functions, e.g. the daily running light or position light, and for the low beam/high beam lighting, a main light source (4) designed for the said low beam/high beam lighting, and a secondary light source (3) designed for the signal light functions. Between the secondary light source (3) and the reflector (2), a micro-lens (1) is situated, configured to increase the diffusion of light emitted by the secondary light source (3) before it falls onto the reflector (2).
