Abstract
Systems, vehicles, and methods for controlling light are provided. In an exemplary embodiment a vehicle with a cabin includes a light senor positioned within the vehicle, where the light sensor is configured to send a light intensity signal. A lamp module is positioned within the vehicle, where the light sensor is in communication with lamp module. The lamp module is configured to trigger a darkness lighting scheme when the light intensity signal is at about a darkness set value or less. A lamp is positioned within the cabin, where the lamp is in communication with the lamp module. The lamp is configured to emit a darkness spectrum when the lamp is activated and when the lamp module triggers the darkness lighting scheme. The darkness spectrum has a maximum illumination wavelength less than about 555 nanometers.
