The illuminated cabinet soffits and aprons each include at least one pocket formed therein for removably placing a panel capable of transmitting light therethrough. The pockets may be formed by cutting a saw kerf between the two opposite panel faces, by separating the front and rear sheets of the panel with spacers, or by adding spacers to the back of a front sheet and attaching a series of webs to the spacers. The front of each panel includes at least one light passage therein. The light passage may have any regular or irregular geometric shape, or may be in the outline of a caricature, an object or symbol relating to an occupation or hobby, etc. The light passage through the rear of the panel may be any desired shape. Various attachments may be provided for removably attaching the panels to the cabinets for interchanging the panels.
