Abstract
In front of the driver there is arranged a screen (20) with a variable transmission coefficient. The headlamps (10, 11) of the vehicle send out periodic pulses of short duration with respect to the period. The transmission coefficient of the screen (20, 23, 24) varies in such a way that it is transparent during the duration of the light pulses and that the screen is substantially less transparent between these pulses.
