The outer housing includes a front surface having a front opening and an inner surface that defines an adjustment cavity having a truncated spherical shape. The inner housing has a truncated spherical shape and is at least partially received within the adjustment cavity. The inner housing defines a light recess therein and includes a front cover having an aperture defined therein. The front cover at least partially defines the light recess. The light member defines a light axis. The light axis and the inner housing axis are not co-axial and not parallel and form an angle therebetween. The inner housing is adjustable between a home position and a plurality of adjustment positions. ## Claims ### Claim 1 A lighting assembly comprising: an outer housing that defines an outer housing axis, wherein the outer housing includes a front surface that defines a front opening therein and an inner surface that defines an adjustment cavity having a truncated spherical shape, an inner housing having a truncated spherical shape, wherein the inner housing defines an inner housing axis and is at least partially received within the adjustment cavity of the outer housing, wherein the inner housing defines a light recess therein and includes a front cover having an aperture defined therein, wherein the front cover at least partially defines the light recess, and a light member positioned within the inner housing, wherein the light member defines a light axis, wherein the light axis and the inner housing axis are not co-axial and not parallel and form an angle therebetween, wherein the inner housing is adjustable between a home position and a plurality of adjustment positions. ### Claim 2 (depends on 1) The lighting assembly of claim 1 wherein in the home position the inner housing axis and outer housing axis are co-axial, and wherein the inner housing axis and outer housing axis are not co-axial in any of the adjustment positions. ### Claim 3 (depends on 2) The lighting assembly of claim 2 wherein the light member includes a front lens member having a front surface that defines a center point, wherein in the home position the outer housing axis passes through the center point, and wherein in any of the adjustment positions, the outer housing axis does not pass through the center point. ### Claim 4 (depends on 1) The lighting assembly of claim 1 wherein the front cover has a front surface that slopes inwardly toward the aperture. ### Claim 5 (depends on 1) The lighting assembly of claim 1 wherein the front cover includes adjustment protrusions thereon. ### Claim 6 (depends on 1) The lighting assembly of claim 1 wherein the front cover includes adjustment indentations thereon. ### Claim 7 (depends on 1) The lighting assembly of claim 1 wherein the front surface of the outer housing includes a switch thereon. ### Claim 8 (depends on 1) The lighting assembly of claim 1 wherein the angle is in the range of about 20° and about 70°. ### Claim 9 (depends on 1) The lighting assembly of claim 1 wherein the angle is in the range of about 40° and about 50°. ### Claim 10 (depends on 1) The lighting assembly of claim 1 wherein the light member is spaced from the front cover and the aperture. ### Claim 11 A lighting assembly comprising: an outer housing that defines an outer housing axis, wherein the outer housing includes a front surface that defines a front opening therein and an inner surface that defines an adjustment cavity having a truncated spherical shape, an inner housing having a truncated spherical shape, wherein the inner housing defines an inner housing axis and is at least partially received within the adjustment cavity, wherein the inner housing defines a light recess therein and includes a front cover having an aperture defined therein, wherein the inner housing axis and the aperture are co-axial, and wherein the front cover at least partially defines the light recess, and a light member positioned within the inner housing, wherein the light member defines a light axis, wherein the light axis is not co-axial with the aperture, wherein the inner housing is adjustable between a home position and a plurality of adjustment positions. ### Claim 12 (depends on 11) The lighting assembly of claim 11 wherein the light axis and the inner housing axis are not parallel and form an angle therebetween. ### Claim 13 An aircraft that includes a non-horizontal wall having an opening defined therein, and a lighting assembly positioned in the opening, wherein the light assembly includes an outer housing that defines an outer housing axis, that includes a front surface that defines a front opening therein and an inner surface that defines an adjustment cavity having a truncated spherical shape, an inner housing having a truncated spherical shape, wherein the inner housing defines an inner housing axis and is at least partially received within the adjustment cavity, wherein the inner housing defines a light recess therein and includes a front cover having an aperture defined therein, wherein the front cover at least partially defines the light recess, and a light member positioned within the inner housing, wherein the light member defines a light axis, wherein the light axis and the inner housing axis are not co-axial and not parallel and form an angle therebetween, wherein the inner housing is adjustable between a home position and a plurality of adjustment positions. ### Claim 14 (depends on 13) The aircraft of claim 13 wherein the non-horizontal wall is a portion of a first or business class seat shell. ### Claim 15 (depends on 14) The aircraft of claim 14 wherein the non-horizontal wall is a vertical wall. ### Claim 16 (depends on 15) The aircraft of claim 15 wherein in the home position the inner housing axis and outer housing axis are co-axial and extend generally horizontally, and wherein the inner housing axis and outer housing axis are not co-axial in any of the adjustment positions.
