The invention provides a method for correcting a first light pattern provided by a lighting device (1) with a matrix of light sources (2). This method comprising the steps of providing a test light pattern (10), instructing the light sources (2) to project the test light pattern (10), choosing some key points (11) in the test light pattern (10) and identify the projection of the key points (21) in the projected light pattern (20), comparing the spatial position of the projection of the key points (21) with respect to the spatial position of the key points (11) in the test light pattern (10), thus obtaining a distortion factor and finally applying a correction factor to correct the distortion factor, thus obtaining a corrected light pattern (5), the correction factor being related to the distortion factor obtained in the previous step. The invention also provides an automotive lighting device (1) and an automotive lighting assembly.
