Claim 0:
1. A method for operating an automotive lighting device including at least a first light module and a second light module, with each one of the light modules including solid-state light sources, the method comprising:
providing a first preliminary current profile to feed the first light module, the first preliminary current profile having a first flux mean value;
estimating a first preliminary derating time associated to the first preliminary current profile;
providing a second preliminary current profile to feed the second light module, the second preliminary current profile having a second flux mean value;
estimating a second preliminary derating time associated to the second preliminary current profile, the second preliminary derating time being higher than the first preliminary derating time;
feeding the first light module with a first current profile which provides a flux mean value lower than 0.96 times the first flux mean value; and
feeding the second light module with a second current profile which provides a flux mean value higher than 1.04 times the second flux mean value.
