Illumination device (10, 20) for a vehicle headlamp, wherein the illumination device (10, 20) provides headlamp levelling for a vehicle headlamp, the illumination device (10, 20) comprises:
- at least one primary light module (100) configured to emit light in a main direction (X), wherein the primary light module (100) is rotatable around a rotation axis (RA),
- a moveable shield cover (200) for shielding the primary light module (100),
- a motion device (300) for moving simultaneously the primary light module (100) around the rotation axis (RA) and the shield cover (200) with respect to each other between
- non-illuminating positions (P1a, P1b, P2a) of the primary light module (100), wherein the shield cover (200) is in front of the at least one primary light module (100), and
- illuminating positions (P3a, P4a) of the light module (100), wherein the shield cover (200) is moved away from the light path of the light module (100)

wherein in each illuminating position (P3a, P3b, P4a) the at least one primary light module (100) is in a defined angular position of a determined operating angular range around the rotation axis (RA) in order to project the light distribution in different angular positions in front of the illumination device (10, 20) to allow a headlamp levelling for a vehicle headlamp.
