A lighting device such as a vehicle lighting device can be configured to be easily adapted to design changes in order to comply with various required or desired luminous intensity distributions. Light emitted from a light source at a large angle with respect to a main optical axis of the light source is more significantly condensed closer to the main optical axis than is the light emitted from the light source at a relatively smaller angle with respect to the main optical axis of the light source. The lighting device can include a lens which has a first lens cut and a second lens cut. The first lens cut can allow light emitted from the light source at a relatively smaller angle with respect to the main optical axis of the light source to pass therethrough. The second lens cut is arranged outside the first lens cut so as to condense light, emitted from the light source at a larger angle, close to the main optical axis of the light source.
