The invention describes an automotive LED lighting module (1) comprising an LED lamp (10) comprising a number of light-emitting diodes (100); a first driver module (11) configured to drive the LED lamp (10) at a first DC voltage level (U_hi); a second driver module (12) configured to drive the LED lamp (10) at a second DC voltage level (U_lo), which second DC voltage level (U_lo) is lower than the first DC voltage level (U_hi); and a switch arrangement (13, 130) comprising an interface (151, 152) for connection to a two-level DC voltage supply (PS), and wherein the switch arrangement (13, 130) is configured to connect the first driver module (11) to the LED lamp (10) when the input voltage is at a first level (U_hi), and to connect the second driver module (12) to the LED lamp (10) when the input voltage level is at a second level (U_lo). The invention further describes an automotive lighting system (2) of a vehicle (3), and a method of operating an automotive LED lighting system (2).
