• the first condition is that an outside temperature of the vehicle is equal to or lower than a predetermined temperature at which the road surface may freeze,
• the second condition is that a brightness of light reflected toward the vehicle from an area illuminated by a headlight of the vehicle is equal to or lower than a predetermined brightness,
• the third condition is that at least one of an anti-lock brake control, which suppresses wheels of the vehicle from locking, a skid suppress control, which suppresses the vehicle from skidding, and a traction control, which suppresses wheels of the vehicle from spinning, has been activated during the most recent predetermined distance traveled by the vehicle, and
• the controller performs a glare reduction control that stops irradiation of at least a part of the patterned light, reduces the amount of light of at least a part of the patterned light, or changes a pattern of at least a part of the patterned light when the plurality of conditions is satisfied.
