A method and device for controlling vehicle interior lighting as a function of certain lighting-relevant states, in which the respective turning-on or turning-off process takes place with dimming. The dimming parameters, such as turning-on or turning-off dimming time or desired final brightness, are selected in advance as a function of the vehicle state that activated the control process, which permits a highly variable and situation-specific lighting control. The lighting control unit, depending on signals from a sensor group and according to a program stored in a program memory, controls a lighting device through a controllable switch.

A circuit arrangement for an anti-theft alarm for vehicles which emits optical signals to the outside by means of the driving direction indicator lights of the vehicle and also permits driving direction changes to be displayed. Actuation of the indicator lights is cancelled by the anti-theft alarm for the duration of the direction flashing indication.
