A vehicular adjustable lighting unit (102, 902), comprising: a lighting feature (104, 402, 502), configured to rotate around a first axis of rotation (106, 506) and comprising a first contact surface (110A, 110B, 416A, 416B, 510A, 510B); and a face cam (114, 302, 404, 602), configured to rotate around a second different axis (116, 304, 422, 608) of rotation, and comprising a second contact surface (118, 302, 414 606), wherein the second contact surface is at an oblique angle with respect to the second axis of rotation; wherein: the lighting unit is configured such that the first contact surface contacts the second contact surface and rotation of the face cam around the second axis of rotation causes the second contact surface to displace the first contact surface thereby adjusting the angular displacement of the lighting feature around the first axis of rotation; the lighting feature comprises a locking feature (112A, 112B, 512A, 512B) configured to abut the face cam in order to resist changes to the rotational position of the face cam and the lighting feature; and the face cam comprises one or more corresponding elements (122, 314A, 314B, 316, 610) configured to interact with the locking feature so as to resist changes to the rotational position of the face cam, wherein the corresponding elements are disposed along a circumference of the face cam. a lighting feature (104, 402, 502), configured to rotate around a first axis of rotation (106, 506) and comprising a first contact surface (110A, 110B, 416A, 416B, 510A, 510B); and a face cam (114, 302, 404, 602), configured to rotate around a second different axis (116, 304, 422, 608) of rotation, and comprising a second contact surface (118, 302, 414 606), wherein the second contact surface is at an oblique angle with respect to the second axis of rotation; wherein: the lighting unit is configured such that the first contact surface contacts the second contact surface and rotation of the face cam around the second axis of rotation causes the second contact surface to displace the first contact surface thereby adjusting the angular displacement of the lighting feature around the first axis of rotation; the lighting feature comprises a locking feature (112A, 112B, 512A, 512B) configured to abut the face cam in order to resist changes to the rotational position of the face cam and the lighting feature; and the face cam comprises one or more corresponding elements (122, 314A, 314B, 316, 610) configured to interact with the locking feature so as to resist changes to the rotational position of the face cam, wherein the corresponding elements are disposed along a circumference of the face cam. the lighting unit is configured such that the first contact surface contacts the second contact surface and rotation of the face cam around the second axis of rotation causes the second contact surface to displace the first contact surface thereby adjusting the angular displacement of the lighting feature around the first axis of rotation; the lighting feature comprises a locking feature (112A, 112B, 512A, 512B) configured to abut the face cam in order to resist changes to the rotational position of the face cam and the lighting feature; and the face cam comprises one or more corresponding elements (122, 314A, 314B, 316, 610) configured to interact with the locking feature so as to resist changes to the rotational position of the face cam, wherein the corresponding elements are disposed along a circumference of the face cam.
