Vehicle light control device

A vehicle light control device mounted on a vehicle to control lighting of a light of the vehicle based on illuminance around the vehicle, comprising:

• an infrared sensor that detects an infrared ray around the vehicle;
• an infrared illuminance detector that detects infrared illuminance from an output of the infrared sensor;
• a visible-light sensor that detects visible light around the vehicle;
• a visible-light illuminance detector that detects visible-light illuminance from an output of the visible-light sensor;
• a storage in which a first lighting threshold is stored;
• and
• a controller that controls the lighting of the light based on the infrared illuminance detected by the infrared illuminance detector, the visible-light illuminance detected by the visible-light illuminance detector, and the first lighting threshold stored in the storage,
• wherein the controller calculates a illuminance difference between the infrared illuminance detected by the infrared illuminance detector and the visible-light illuminance detected by the visible-light illuminance detector, and the controller turns on the light when the illuminance difference is less than or equal to the first lighting threshold.
