The device has two light sources such as LEDs, where each LED (1a) is associated with an optical device. The optical device includes primary guides (2a, 2b) having light rays entrance surfaces, and an output section to propagate light rays in the form of primary beams of collimated rays to exit the section. A deflection unit directs each beam toward a common propagation portion, and produces a secondary beam for each primary beam, where overall directions of the envelopes of the secondary beams are parallel, and the envelopes of the secondary beams cut partially. |
