Abstract

The invention relates to an LED signaling device (10) with a two-wire interface (25) for connecting the LED signaling device (10) to a control unit (200) via a two-wire line (100). According to the invention, the LED signaling device (10) is designed to transmit a diagnostic message to the control unit (200) by changing an electric current (Ii) that flows via the two-wire line (100).
