Controlling brightness of illuminated switches in motor vehicle by reducing brightness when headlights are switched on

摘要

When the vehicle headlights are switched on, the brightness of the illuminated switches is reduced. When the headlights are switched off, the brightness of the illuminated switches is increased. The switch for the headlights (1) is logically connected to the illuminated elements (2) of switches so that this brightness control occurs. The brightness of displays is similarly controlled.
