Abstract

A method for controlling a lighting brightness of a lit motor vehicle instrument is described in which a viewing direction of a driver is ascertained. From the viewing direction of the driver, a direct field of vision and a peripheral field of vision are ascertained. The lighting brightness of the motor vehicle instrument is increased, if it lies in the direct field of vision of the driver. The method may be implemented in a motor vehicle.
