Abstract
In a method for operating an access arrangement (ZA) for a vehicle (FZ), access to the vehicle can be obtained by a mobile identification transmitter (IDG). With this method, first an ambient brightness around the vehicle is determined. Furthermore, the presence of an authorized mobile identification transmitter in an approach region (ANB, ANB2) around the vehicle is examined. Finally, an activation signal (LSS) for an illumination source (BL) of the vehicle is issued when the ambient brightness drops below a predetermined brightness value and the presence of an authorized mobile identification transmitter is detected in the approach zone. In this way, efficient activation of the illumination source can be achieved.
