1. A method for operating an automotive lighting device that applies at least one solid-state light source comprising:
providing a plurality of sensors that are configured to provide some device data;
providing a control unit configured to receive and process said device data;
generating an estimated condition of the automotive lighting device based on said device data, the estimated condition derived from indirect data without a dedicated sensor; and
controlling an operation parameter of the automotive lighting device using the estimated condition; and
resulting in a decrease of current that is fed into said solid-state light source such that output flux value and an operation temperature value decreases, accordingly.
