Abstract
The light device contains first and second rows of light sources wherein rows are arranged next to each other, collimating elements associated with the light sources to convert their generated light to collimated light, and a light guide to bind the collimated light and emit it from the light guide output surface. Between the collimating element output and the light guide output surface, an optical means is arranged to divide the collimated light to at least two individual, spatially separated light beams, wherein the first light beam is formed by part of the collimated light passing by the optical means, and the second light beam is produced by passing another part of the collimated light through a refractive surface of the optical means. The first and second light beams are displayed on the output surface in the form of separate bands, namely the first and second band (A, B).
