Abstract
A vehicle lighting device can include a bulb or a light source, a projector lens, a first reflection surface which reflects light toward the projector lens and collects the reflected light, a shade including an upper rim, the upper rim being movable between a light blocking position and a retracting position. The lighting device can also include a second reflection surface which reflects light downward when the shade is in the light blocking position, and a third reflection surface which reflects light forward to allow the reflected light to be emitted forward, when the shade is in the light blocking position. The device can also include a pair of left and right fourth reflection surfaces which reflect light in diagonally forward right and left directions, respectively, to allow the reflected light to be emitted in the diagonally forward right and left directions, when the shade is in the light blocking position.
