A lighting device for a vehicle, comprising: a light emission part; a reflector disposed above the light emission part and configured to reflect a first portion of light emitted from the light emission part; a first lens having a first incident face through which light (L1a) reflected by the reflector enters; a second lens disposed higher than the first lens in an up-down direction, when the lighting device is installed in the vehicle, and having a second incident face through which a second portion of the light emitted from the light emission part enters, wherein a distance between the light emission part and the second incident face in a horizontal direction, when the lighting device is installed in the vehicle, is smaller than a distance between the light emission part and the first incident face in the horizontal direction; a first light shielding member disposed between the first lens and the second lens in the up-down direction; a second light shielding member whose position in the horizontal direction is between the position of the light emission part and the position of the first lens; a third light shielding member whose position in the horizontal direction is between the position of the light emission part and the position of the second lens; and an actuator configured to switch the lighting device between a light-shielded state and a non-light-shielded state by moving the second light shielding member and the third light shielding member, wherein, when the lighting device is in the light-shielded state, the second light shielding member shields a portion (L1b) of light (L1a) advancing from the reflector towards the first incident face, and the third light shielding member shields the second portion of the light advancing from the light emission part towards the second incident face, wherein, when the lighting device is in the non-light-shielded state, the second light shielding member does not shield the light (L1a) advancing from the reflector towards the first incident face, and the third light shielding member does not shield the second portion of the light. a light emission part; a reflector disposed above the light emission part and configured to reflect a first portion of light emitted from the light emission part; a first lens having a first incident face through which light (L1a) reflected by the reflector enters; a second lens disposed higher than the first lens in an up-down direction, when the lighting device is installed in the vehicle, and having a second incident face through which a second portion of the light emitted from the light emission part enters, wherein a distance between the light emission part and the second incident face in a horizontal direction, when the lighting device is installed in the vehicle, is smaller than a distance between the light emission part and the first incident face in the horizontal direction; a first light shielding member disposed between the first lens and the second lens in the up-down direction; a second light shielding member whose position in the horizontal direction is between the position of the light emission part and the position of the first lens; a third light shielding member whose position in the horizontal direction is between the position of the light emission part and the position of the second lens; and an actuator configured to switch the lighting device between a light-shielded state and a non-light-shielded state by moving the second light shielding member and the third light shielding member, wherein, when the lighting device is in the light-shielded state, the second light shielding member shields a portion (L1b) of light (L1a) advancing from the reflector towards the first incident face, and the third light shielding member shields the second portion of the light advancing from the light emission part towards the second incident face, wherein, when the lighting device is in the non-light-shielded state, the second light shielding member does not shield the light (L1a) advancing from the reflector towards the first incident face, and the third light shielding member does not shield the second portion of the light.
