Claim 12:
13. A light-emitting trim panel comprising:
a first layer that is configured to be exposed and come in contact with a vehicle occupant;
a translucent polymer sheet layer providing a protective layer including a protective layer inner surface and protective layer outer surface and a plurality of cavities configured to accept a plurality of light emitting diodes (LEDs) arranged to generate light;
a plurality of LEDs configured to align and project into said cavities;
wherein said cavities are formed from a plurality of upstanding portions and said LEDs have a thickness (tLED), the translucent polymer sheet has a protective layer thickness tPL and the height T of the upstanding portions is provided by the following relationship:, T
