Vehicle lavatory UV light sanitization system

A vehicle lavatory monument assembly comprising:

• an enclosure that includes a plurality of walls that cooperate to define a lavatory interior, wherein an entry door is positioned on one of the plurality of walls, and
• a UV sanitization system that includes a first light module positioned in the lavatory interior, wherein the first light module includes an ultraviolet light source that emits ultraviolet light rays and a lens member including a first portion with a first thickness and a second portion with a second, different thickness, a first reflective surface comprising a reflective coating disposed beneath a layer of transparent material configured thereon, a first direct surface to be sanitized, and a first indirect surface to be sanitized, wherein the first portion of the lens member is configured to direct ultraviolet light rays to the first direct surface to be sanitized, wherein the second portion of the lens member is configured to direct ultraviolet light rays to the first reflective surface, wherein the first reflective surface is angled to direct ultraviolet light rays to the first indirect surface to be sanitized, wherein the first reflective surface is located adjacent to a non-reflective surface, wherein the first reflective surface is not parallel to the non-reflective surface, and wherein the layer of transparent material creates a substantially continuous surface with the non-reflective surface,
• wherein the UV sanitization system includes an activation assembly that includes a manual activation switch configured to activate the UV sanitization system, wherein the manual activation switch is located outside the lavatory interior, wherein the activation assembly includes an indication system that is configured to indicate a UV sanitization status of the lavatory interior, wherein the indication system includes a plurality of indication lights that include a first indication state and a second indication state, wherein the first indication state indicates that the vehicle interior is clean, and wherein the second indication state indicates that the vehicle interior is not clean, wherein the manual activation switch is disabled when the lavatory interior is occupied, and wherein the manual activation switch is disabled when the entry door is locked.
