A method is provided for fabricating resin-filled components, which comprises a multi-element arrangement of a thermoformed plastic sheet with a "second-surface" screen-printed graphic, which formed sheet can receive a light-directing apparatus, and the molded-resin is applied so as to secure the apparatus and provide stability to the overall structure or component. The method is particularly adapted with respect to the fabrication of graphic-display illuminated buttons for use within automotive vehicles.
