A method for controlling a lighting system of a motor vehicle, the lighting system with a plurality of elementary light sources each selectively controllable in order to emit an elementary light beam, the method includes detecting a road sign by a sensor system of the motor vehicle; estimating a passing duration between the instant the road sign is detected and a future instant at which the motor vehicle will pass the detected road sign; controlling the elementary light sources of the lighting system of the host vehicle in order to emit a pixelated light beam, with a portion of the elementary light sources being controlled, as a function of the passing duration, in order to generate a lower intensity zone extending in the vicinity of the road sign.
