special plastic sheet and additional parts for inscribing or retaining advertising messages on the two surfaces of the special sheet are retained by an aluminium frame where the electronic illumination elements are contained, which illuminate perimetrically the special sheet through its thickness only; the sheet then illuminates in turn the advertising messages from the back and is supported on special flexible footings which are in turn retained onto the roof of the vehicle with a double-sided self-adhesive tape. |
