A vehicle lighting unit includes LEDs mounted on a substrate, and an elongated inner lens configured to receive light from the LEDs and guide the light along its lengthwise direction so as to emit light from its front surface. The inner lens includes a first light guiding section extending in the left-to-right direction and a second light guiding section extending in the vertical direction, and a bending section between the first and second light guiding sections. The bending section includes a first reflection surface and a second reflection surface. The first and second reflection surfaces internally reflect light toward the first and second light guiding sections, respectively. The LEDs include a first LED and a second LED, disposed in the rear of the first reflection surface and the second reflection surface, respectively.
