8 . The lighting device of claim 7 , wherein the light-blocking unit comprises a coating layer applied to (1) a first surface of the outer lens unit facing in a first direction or (2) a second surface positioned to face in a second direction opposite to the first direction.

9 . The lighting device of claim 7 , wherein the light-blocking unit comprises a film insert-molded onto (1) a first surface of the outer lens unit facing in a first direction or (2) a second surface positioned to face in a second direction opposite to the first direction.

10 . The lighting device of claim 8 , wherein the light-transmitting portion is formed by laser etching or laser perforation.

11 . The lighting device of claim 1 , wherein the light-blocking unit is disposed between the outer lens unit and the light source unit.

12 . The lighting device of claim 1 , further comprising an inner lens portion disposed between the outer lens unit and the light source unit.

13 . The lighting device of claim 1 , wherein the housing unit is mounted on a front portion or a rear portion of a vehicle body of the vehicle.

14 . The lighting device of claim 1 , further comprising a control unit electrically connected to (1) the light source unit and (2) one or more vehicle electronic components and configured to receive operating signals from the one or more vehicle electronic components and control the light source unit.

15 . The lighting device of claim 14 , wherein the control unit is configured to an ON/OFF operation of the light source unit to implement a welcome mode or a goodbye mode of the vehicle based on an ignition ON/OFF signal of the vehicle, in response to receiving an operation signal from one of the one or more vehicle electronic components responsible for operating an ignition ON/OFF operation of the vehicle.

16 . The lighting device of claim 14 , wherein the control unit is configured control an ON/OFF operation of the light source unit to implement a daytime driving mode or a nighttime driving mode of the vehicle based on an illumination value received from the one or more vehicle electronic components, in response to receiving an operation signal from one of the one or more vehicle electronic components responsible for detecting external illumination of the vehicle.

17 . The lighting device of claim 14 , wherein the control unit is configured to control an ON/OFF operation of the light source unit to indicate a stop state of the vehicle in response to receiving an operation signal from one of the one or more vehicle electronic components responsible for detecting a distance between a pedestrian outside the vehicle and the vehicle.

18 . The lighting device of claim 1 , wherein the first outer lens portion comprises:

a lens body portion coupled to the housing unit and covering the opening; and

a lens mounting portion recessed on an outer surface of the lens body portion, wherein the second outer lens unit is mounted on the lens mounting portion,

wherein the lens mounting portion has a coupling groove portion recessed on an outer surface thereof, and

wherein the second outer lens unit has a coupling protrusion portion protruding from an outer surface thereof and inserted into the coupling groove portion.

19 . A lighting device for a vehicle, comprising:

a housing unit having an opening;

an outer lens unit coupled to the housing unit and configured to cover the opening of the housing unit;

a light source unit housed at the housing unit and configured to emit light toward the outer lens unit; and

a light-blocking unit disposed on the outer lens unit and configured to partially block the light emitted from the light source unit,

wherein the outer lens unit comprises:

a first outer lens portion; and

a second outer lens portion coupled to the first outer lens portion and including the light-blocking unit, and

wherein the first outer lens unit comprises:

a lens body portion coupled to the housing unit and covering the opening; and

a lens mounting portion recessed on an outer surface of the lens body portion, wherein the second outer lens unit is mounted on the lens mounting portion.

20 . The lighting device of claim 19 , wherein:

the lens mounting portion has a coupling groove portion recessed on an outer surface thereof, and

the second outer lens unit has a coupling protrusion portion protruding from an outer surface thereof and inserted into the coupling groove portion.
