Which of the control lights visible in the illustration applies to the front fog lights?

Green warning light B relates to the front fog lights: a headlamp symbol with diagonal rays going downwards, crossed by a wavy line meaning fog. Warning light A with two arrows means the indicators, and C, that is, two small lamps with rays pointing outwards, means the sidelights.

Front fog lights are meant for driving in reduced visibility - in fog, heavy rain or a snowstorm - together with dipped headlights or instead of them. In good weather you may use them only from dusk to dawn on a winding road marked with the appropriate signs. Switched on when they are not needed, they dazzle other drivers.
