A lighting module (20) comprising a power line (OUT+) for receiving a power supply current and a ground line (GND, OUT-). The lighting module (20) comprises a segmentation point (200a) for cutting the lighting module (20) into two parts, wherein a first set of light sources (210a) is upstream of the segmentation point (200a), and at least a second set of light sources (210a) is downstream of said segmentation point (200a), wherein the first (210a) and second (210b) sets of light sources are connected in series. In particular, the lighting module (20) comprises a resistive element (206a) connected to the intermediate point between the first (210a) and the second (210b) set of light sources, and the ground line (GND, OUT-). This resistive element (206a) is configured in such a way that: a) when the lighting module (20) has not been cut at the segmentation point (200a), the resistive element (206) has a resistance which is greater than the resistance of the portion of the lighting module (20) downstream of the segmentation point (200a), and b) when the lighting module (20) has been cut at the segmentation point (200a), the resistive element (206) has a resistance which is less than the resistance of the portion of the lighting module (20) downstream of the segmentation point (200a).
