The invention relates to a method of producing roof panelling consisting in incorporating one or more electroluminescent strips (8) into the roof panel (13) forming process. Said process consists in positioning and fixing a lining (11) to a pre-formed panel support (3). The electroluminescent strips (8), which form a lighting system in the roof panelling (13), are disposed between the panel support (3) and the lining (11). Each of said strips is provided with a flat cable (10) and a connector which pass through an opening (5) in the panel support (3), the connector (9) being disposed at the end of said cable. The connector, which is concealed by the rear face of the panel, provides a connection to the power supply in the roof of the vehicle containing said panelling (13).
