When the system detects a vehicle within the area illuminated by the high beams, it disables/enables 8 upper and 16 lower LEDs on each side to partiallyblock light from the high-beam headlamps so that they don’t directly project onto a preceding or oncoming vehicle. In this way, it helps to provide the driver with good visibility by illuminating road signs and other objects in front of the vehicle, without dazzling other vehicles.
