The present invention refers to a detector device for detecting a status of at least a first electronic element of an automotive lighting device. This detector device comprises a status detection unit configured to detect a status of the at least first electronic element and to generate a reference signal which depends at least on the status of the first electronic element. It also comprises a comparison signal generator configured to generate a comparison signal and a comparison unit configured to generate a pulse-width modulation signal by comparing the reference signal with the comparison signal.
