A vehicle lighting unit (1) can include a DRL function while the light emission unit thereof can be miniaturized more than the conventional vehicle headlamps. The vehicle lighting unit (1) can include a headlamp (HL) unit having a HL light guiding lens (5) and a daytime running lamp (DRL) unit (3). The HL light guiding lens (5) can include a light incident surface (51) in front of a light source LED (4) for HL, a front reflection surface (52), a rear reflection surface (54), and a light-transmitting section (55). The front reflection surface (52) can internally reflect light from the light incident surface (51) obliquely rearward and downward. The rear reflection surface (54) can internally reflect the light from the front reflection surface (52). The light-transmitting section (55) is disposed between the front and rear reflection surfaces (52, 54) in terms of its vertical direction. The DRL unit (3) can be disposed behind the light-transmitting section (55), so that the light from the DRL unit (3) can pass through the light-transmitting section (55) to be projected forward.
