1. A cabin light for a machine, the cabin light comprising: a panel adapted to couple with a light source, the panel including: a pair of longitudinal portions extending along a longitudinal axis of the cabin light, each longitudinal portion including a first surface, a second surface at an offset from the first surface, and a first width, wherein the first surface defines a second width, such that the first width is greater than the second width by a factor of at least two; a first lateral portion extending between the pair of longitudinal portions along a lateral axis of the cabin light, the first lateral portion defining a first length along the longitudinal axis, wherein the first lateral portion includes a first raised surface extending along at least a portion of the first length; and a second lateral portion extending between the pair of longitudinal portions along the lateral axis of the cabin light, the second lateral portion being disposed opposite the first lateral portion, the second lateral portion defining a second length along the longitudinal axis, wherein the second lateral portion includes a second raised surface extending along at least a portion of the second length; a cover fixedly coupled to the panel, wherein the cover is in alignment with the light source, such that the cover allows passage of light emitted by the light source therethrough; and a switch between the cover and the second lateral portion of the panel in a longitudinal direction of the panel, wherein the panel further includes an intermediate portion between the cover and the switch in the longitudinal direction of the panel, wherein the cover includes a first cover surface, a second cover surface, and a third cover surface between the first cover surface and the second cover surface, each of the first, second, and third cover surfaces extending from the first side of the cover to the second side of the cover, each of the first cover surface and the second cover surface being inclined with respect to the third cover surface which is substantially planar, wherein the switch includes a first switch surface, a second switch surface, and a third switch surface extending between the first switch surface and the second switch surface, each of the first switch surface and the second switch surface being inclined with respect to the third switch surface which is substantially planar, and wherein, in the longitudinal direction of the panel, the first cover surface is aligned with the first switch surface, the second cover surface is aligned with the second switch surface, and the third cover surface is aligned with the third switch surface.
