Abstract

An illumination system for a harvesting implement including two or more lighting devices, each lighting device coupled to the harvesting implement and configured to illuminate an area of crop engagement, a path of the harvesting implement, or both. The illumination system additionally includes a controller coupled to the harvesting implement and communicatively coupled to the lighting devices. The controller is configured to control an operation of the illumination system to provide a first pre-set illumination pattern based on a first operating state of the harvesting implement. The controller is further configured to receive an input indicative of a change in the operating state of the harvesting implement. Further, the controller is configured to, in response to receipt of the input, control the operation of the illumination array to provide a second pre-set illumination pattern based on the change in the operating state.
