A tab is cut into a sheet of transparent material. The tab has a free end and a fixed end. A source of light is attached to the tab and the tab and the sheet are displaced along the z-axis of the sheet to direct light from the source into an edge of the sheet. The tab can include conductive traces for electrical connection to the light source or other electrical devices on the sheet. A variable display device adjacent the sheet is viewed through the sheet and the sheet with attached light source provides front lighting for the variable display device.
