Claim 13:
14. An automotive lighting device comprising:
a first light module comprising a plurality of solid-state light sources;
a second light module comprising a plurality of solid-state light sources;
a control element configured to:
provide a first preliminary current profile to feed the first light module, the first preliminary current profile having a first flux mean value;
estimate a first preliminary derating time associated to the first preliminary current profile;
provide a second preliminary current profile to feed the second light module, the second preliminary current profile having a second flux mean value;
estimate 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;
feed 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
feed 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.
