US Patent 10427592 Car light sensor warning for headlights

A method and system for controlling exterior lights on a vehicle. The method includes receiving an input indicative of a desired mode of operation of the exterior lights from a user-selectable input device. The user-selectable input device includes an on-setting, an off-setting, and an automatic-setting. The method further includes receiving sensor data indicative of a level of visibility outside the vehicle, comparing the sensor data to a threshold, and generating, by an electronic processor, a notification indicative of an improper positioning of the user-selectable input device when the sensor data indicates that the level of visibility is less than the threshold and the user-selectable input device is positioned in the off-setting.
