Abstract
An automatic lighting device includes an illuminance detector for detecting an external illuminance around a vehicle, a light controller for turning on/off a vehicular light, a driver's characteristics detector for acquiring information about driver's physical characteristics, and a threshold setting element for setting the illuminance threshold in accordance with the driver's physical characteristics. The controller turns on the light when the external illuminance is not more than the illuminance threshold.
