Abstract: An advertising display for use above the roof of a vehicle comprises a rigid elongated and enclosed advertising member, which is of substantially triangular cross section and which can be reversibly mounted on a metallic roof with the use of magnets affixed within receptacles in the base of the display. Apparatus is provided for storing a plurality of the advertising members in a space-conserving fashion.

Abstract: A rigid aerodynamic advertising member is removably mounted to either the tailgate or vertical side of the bed of a pick-up truck with a mounting bracket coupled to rigid braces attached to the advertising member, with the dimension between the braces being sufficient to insure rigidity while the truck is underway.

Abstract: The protective shield includes an elongated transparent shield member and a molded forearm support member having a forearm concavity spaced from the shield member by a dimension which provides additional protection to the person using the protective shield.

Abstract: An advertising display for use above the roof of a vehicle comprises a rigid aerodynamic member, which tapers rearwardly to a trailing edge with an upstanding brace extending into the aerodynamic member and with a window mount fixed to the brace and having a lateral hook portion dimensioned to pass across the top of one of the vehicle's windows. At least one surface of the aerodynamic member defines an area to which an advertising medium can be affixed.

Abstract: A lighting system for a translucent plastic car top sign having three side panels forming a truncated triangular pyramid and a top is disclosed. A convex reflector surface depends from the top and has three electric lamps oriented to be aligned with the apexes of the triangular pyramid such that each panel is illuminated by overlapping of direct and reflected light from the lamps. A translucent diffuser dome may be disposed over the reflector and lamps.

Abstract: An advertising sign holder for attachment to a vehicle roof is molded from a translucent plastic sheet. A triangular base flange has a hollow truncated pyramid with a triangular base integral therewith. The pyramid includes an integral top. Suction cups are attached to the corners of the base flange for the dual function of attaching the sign to a vehicle roof and maintaining separation of a plurality of signs nested together for storage. An electric light disposed within the pyramid portion provides illumination of the sign holder.
