Abstract: A headlight determination apparatus includes a camera device, a target light recognition device, and a changing device. The camera device captures an image ahead of a vehicle at a predetermined frame rate. The target light recognition device recognizes target light from the image captured by the camera device. The changing device changes a wavelength of headlight of the vehicle by using a predetermined period slower than the predetermined frame rate. When the wavelength of the headlight is different from a wavelength of the target light and/or when a period of the wavelength of the headlight does not match a period of the wavelength of the target light, the target light recognition device recognizes that there is target light other than the headlight in front of the vehicle and controls light distribution of the headlight when there is target light other than the headlight in front of the vehicle.
