A decal assembly includes a film, a power source including a positive contact and a negative contact, a light having a positive terminal and a negative terminal, and a layer of electrically conductive ink applied to the film, the layer of electrically conductive ink forming a line to connect the positive contact of the power source to the positive terminal of the light, and to connect the negative contact of the power source to the negative terminal of the light.

A method of securing at least one document to a window involves retaining the at least one document in a retaining portion of a document holder by inserting the at least one document through an opening defined along a retaining portion side edge of the retaining portion. A length of the opening is substantially equal to a length of the retaining portion side edge. The method further involves inserting a securing portion of the document holder extending from the retaining portion into an opening defined by a windowpane of the window when the windowpane is in an open position. The method further involves, when the securing portion is inserted into the opening defined by the windowpane, moving the windowpane from the open position to a substantially closed position to engage the securing portion and thereby secure the document holder at the window.

The document display holder is intended to provide users with a device that can hold and display a business card and/or memo for motored vehicles on the vehicle's windshield, to ensure effective communication between the vehicle driver and the general public. To accomplish this, the device includes a rectangular frame made of a clear rigid material, wherein a slot is provided within for placing the business card or any memo. The device further comprises one or more fasteners for mounting onto a windshield or any smooth surface with a lasting hold. Thus, relevant contact information may be displayed from inside of the vehicle for easy visibility and swift contact in case of an emergency. Furthermore, the display holder is versatile and customizable, wherein any information ideal for companies and government entities with fleet vehicles, traveling businessmen, and/or other vehicle related ventures may be displayed.
