Abstract: A method for manufacturing an automotive luminous device. This method comprises some steps. A first step comprises providing a housing with a hollow protrusion. A second step comprises providing an auxiliary element in the hollow protrusion. A third step comprises providing a connector receptacle in connection with the auxiliary element. A fourth step comprises inserting a matching connector in the connector receptacle in a detachable way, the matching connector further comprising guiding means. A fifth step comprises placing a luminous module comprising a module connector, the module connector being helped by the guiding means to be connected to the matching connector, thus achieving an electric connection between the module connector and the matching connector. A final step comprises moving the connector receptacle so that the matching connector exits from the connector receptacle.
