A hatchback door for motor vehicles comprising: - a plurality of metal inserts (11, 15, 17) for connection of a pair of hinges for articulation of the hatchback door to the structure of the motor vehicle, - a load-bearing inner panel made of composite plastic material, which defines a rear-window opening, - a top outer panel made of plastic material designed to be glued on the top portion of said load-bearing inner panel, wherein said top outer panel comprises a first layer of transparent plastic material and a second layer of opaque plastic material or of opaque paint, wherein said opaque plastic layer or layer of opaque paint covers only some parts of said transparent layer in such a way that said top outer panel is transparent in a central part thereof overlying said rear-window opening of said load-bearing inner panel and in its peripheral portion that are to function as transparent element for a top set of lights,and - a bottom outer panel made of plastic material glued on the bottom portion of said load-bearing inner panel and having a top portion that is also glued to a bottom portion of said top outer panel in such a way that the top portion of said bottom outer panel is set between said top outer panel and said load-bearing inner panel, - said top set of lights having a load-bearing body with at least one light source and without a transparent outer front element, - the body of said top set of lights being connected to a rear side of said top outer panel, in such a way that said transparent peripheral portion of the top outer panel constitute the front transparent element of said top set of lights, said hatchback door being characterized in that: - said top outer panel is transparent also in peripheral portions that are to function as transparent elements for two lateral sets of lights, - said lateral sets of lights each having a load-bearing body with at least one light source and without a transparent outer front element, - the body of said top set of lights and each lateral sets of lights (24, 25) being connected to a rear side of said top outer panel by a plurality of fixing elements (31A,32) mounted at the inner surface of the top outer panel, in such a way that said transparent peripheral portions of the top outer panel constitute the front transparent elements of said lateral sets of lights (24, 25), - said plurality of metal inserts (11, 15, 17) for connection of a pair of hinges being incorporated in said load-bearing inner panel made of composite plastic material, and being provided also for connection of a lock, at least one gas-operated spring and/or an electric actuator. -
