A vehicular lamp system, comprising a lamp unit comprising a plurality of marker lamp regions, each operable as a different marker lamp, the plurality of marker lamp regions being customizable in arrangement; a configurator that receives a customization of the plurality of marker lamp regions in arrangement and that generates a customized configuration indicating customized arrangement of the plurality of marker lamp regions; and a controller that controls the lamp unit to define the plurality of marker lamp regions in the lamp unit according to the customized configuration and to operate the plurality of marker lamp regions each as the different marker lamp, wherein the configurator displays a settable area that is allowed to be used as a marker lamp region for each marker lamp when receiving the customization.

A vehicular headlamp (1) serving as a lamp fitting includes: a board (40) on which a first light source (41) and a second light source (42) serving as light sources are mounted; a heat sink (20) on which the board (40) is disposed; and a reflector unit (50) that presses the board (40) against the heat sink (20) and reflects a part of light emitted from the first light source (41) and the second light source (42), in which the board (40) has recesses (45) which are recessed portions of side surfaces (40sf) facing each other, the first light source (41) and the second light source (42) are positioned at inner positions with respect to a bottom portion (45B) of each of the recesses (45), and the reflector unit (50) presses parts of the board (40) that are positioned at outer positions with respect to the bottom portion (45B) of each of the recesses (45).

A vehicle headlight (1) includes a light unit (10) and a control unit (CO). As compared with a case where a plurality of predetermined objects is not located in front of a vehicle (100), when the plurality of predetermined objects is located in front of the vehicle (100), the control unit (CO) decreases an amount of light in a first region (91a), (91b), (91c) individually overlapping at least a part of each of the predetermined objects in an ADB light distribution pattern (P1), increases an amount of light in a second region (92a), (92b), (92c) following at least a part of an outer edge of each of the first regions (91a), (91b), (91c), and sets a light increase rate in an overlapping region (93), in which at least a part of one (92a) of two (92a), (92c) of the second regions and the other (92c) of the two second regions overlap each other, to be lower than a sum of a light increase rate in one (92a) of the two second regions and a light increase rate in the other (92c) of the two second regions.
