Systems and methods are provided for identifying light sources at an airport. Light sources are detected in a vehicle camera image. A region of interest (ROI) is determined for each light source based on the location of the light source in the image. A distance and relative angle are determined between each light source and a vehicle camera location. A gray scale version of each ROI is generated based on pre-defined relationships between intensities of red, green, and blue colors in the image and gray color intensities. The gray scale version is compared with pre-defined color histograms to determine a color associated with each light source. Each histogram corresponds to a gray-scale equivalent of an associated color. Context data associated with the image is determined. A light source type is assigned to each of the light sources based on the color of the light source and the context data.
