An automotive lighting device comprising a housing; an electronic substrate comprising an electronic circuit and an edge protrusion comprising electric connection tracks; a light source arranged in the electronic circuit of the electronic substrate; a carrier part and a card edge female connector, wherein: the carrier part comprises attaching means configured to attach the carrier part to the housing; the carrier part comprises a connector zone where the card edge female connector is housed, the connector zone comprising an opening configured to receive the edge protrusion; the edge protrusion is configured to be inserted in the card edge female connector along an insertion direction when the carrier part is assembled on the vehicle; the carrier part comprises a guide element which protrudes from the opening of the connector zone in the same direction as the insertion direction, the guide element being configured to guide the edge protrusion of the electronic substrate towards the connector zone; the housing comprises securing means configured to cooperate with the attaching means in order to attach the carrier part to the housing; the securing means comprises a first securing protrusion and a second securing protrusion that protrude from the housing in a protrusion direction when the housing is assembled on the vehicle and the protrusion direction is different from the insertion direction; the securing means and the attaching means are configured to cooperate as a snap fit connection; characterized in that the attaching means comprises a first attaching leg and a second attaching leg; the first securing protrusion comprises a first hole intended to receive the snap fit connection of the first attaching leg; the second securing protrusion comprises a second hole intended to receive the snap fit connection of the second attaching leg, and the perpendicular projection of the centre of the first hole over the second securing protrusion does not cross the centre of the second hole. a housing;
