Abstract

A light distribution plenum includes a shell having an interior surface substantially defining a cavity. A light source receptor is configured to receive light from a light source into the cavity in use. A first optical avenue is associated with the shell and is configured to direct a portion of the light to a first control device. A second optical avenue is associated with the shell, is spaced from the first optical avenue, and is configured to direct a portion of the light to a second control device. At least one selective optic is at least partially within the light distribution plenum and is configured to interact with at least some portion of the light. An illuminated control assembly including a light distribution plenum, a motor vehicle including an illuminated control assembly, and a method of illuminating first and second control devices are also provided.
