An illumination apparatus for a vehicle is disclosed. The illumination apparatus comprises a trim portion affixed to a surface comprising a first photoluminescent portion and at least one light source. The light source may be configured to emit a first emission at a first wavelength. The first emission may be configured to excite the first photoluminescent portion in a back-lit configuration. The trim portion is configured to mask the first photoluminescent portion from external light sources to prevent excitation of the first photoluminescent portion in the presence of external light sources.
