COVER GLASS FOR LIGHTING ASSEMBLY AND ITS MANUFACTURING PROCESS

A lens according to the invention intended to close an opening of a housing of a lighting and/or signaling device of a motor vehicle. The lens comprises a first layer (5) and a mounting tooth (6) arising from the first layer, the mounting tooth (6) being intended to cooperate with a peripheral rib delimiting the opening, and it comprises a second layer (8) covering the first layer (5) at least at the level of the mounting tooth (6). A first thickness E1 of the first layer (5) is measured at the level of the mounting tooth (6) and a second thickness E2 of the first layer (5) is measured next to the mounting tooth (6). The first thickness E1 is greater than or equal to the second thickness E2.
