A vehicular rotatable lamp assembly includes a main frame, a lighting unit including a rotatable lamp seat holder connected pivotally to the main frame and having a gear-toothed plate, and a drive mechanism including a motor mounted on the main frame for rotating the lamp seat holder to a predetermined angle, a motor gear connected to the motor, and a correction gear meshed between the motor gear and the gear-toothed plate. An angle correction mechanism includes an angle indicator rotating along with the correction gear for indicating a rotating angle of the correction gear, and an angle sensor for detecting the rotating angle of the correction gear. A control unit controls the motor to correct an angular position of the lamp seat holder when the rotating angle detected by the angle sensor is not consistent with the predetermined angle.
