An automotive headlamp module that reduces manufacturing cost and increases availability for low-cost vehicles is provided. The automotive headlamp provides a rotational force to a shield via a DC motor and improves safety during operation by implementing a beam pattern in a low-beam mode when performing a fail-safe function due to breakdown in a high-beam mode or an ADB mode. In particular, the automotive headlamp includes a drum type shield rotatably disposed with respect to a shield housing and has a high-beam protrusion, a low-beam protrusion, and an adaptive driving-beam (ADB) protrusion on an exterior side and a shield disc coupled to the shield that rotates. A housing disc guide is movable in a longitudinal direction of the shield by the shield housing and has an end in contact with the shield disc and a return spring and presses a housing disc to the shield disc with accumulated elastic force.
