A vehicle lighting unit (1, 1A) can emit light rays with at least two different colors from a single line-shaped light emitting part while the light utilizing efficiency can be improved as compared with a conventional lighting unit. The vehicle lighting unit (1, 1A) can include a first LED (2, 21, 21A) and a second LED (2, 22, 2A, 22A) each having a different color; a first light guiding lens (3, 31, 3A, 31A) and a second light guiding lens (3, 32, 3A, 32A) disposed in front of the first LED (2, 21, 21A) and the second LED (2, 22, 2A, 22A), respectively, the first light guiding lens (3, 31, 3A, 31A) and the second light guiding lens (3, 32, 3A, 32A) configured to guide light rays emitted from the first LED (2, 21, 21A) and the second LED (2, 22, 2A, 22A), respectively, to cause the light rays to exit through respective light exiting faces (34, 34A) of the first and second guiding lenses (3, 31, 32, 3A, 31A, 32A) forward; and a diffusion lens (4, 4A) disposed in front of the first light guiding lens (3, 31, 3A, 31A) and the second light guiding lens (3, 32, 3A, 32A), configured to diffuse the light rays exiting from the first light guiding lens (3, 31, 3A, 31A) and the second light guiding lens (3, 32, 3A, 32A) while allowing the light rays to pass therethrough forward. The light exiting faces (34, 34A) of the first light guiding lens (3, 31, 3A, 31A) and the second light guiding lens (3, 32, 3A, 32A) each can be configured to be long and juxtaposed with each other in a direction perpendicular to a lengthwise direction thereof with the lengthwise directions coincide with each other. The diffusion lens (4, 4A) can have a long shape so as to cover the entire front light exiting faces (34, 34A) of the first and second light guiding lenses (3, 31, 32, 3A, 31A, 32A).
