A crop sprayer is an agricultural machine that applies liquid products such as fertilizers and crop-protection agents through a tank, pump, boom, and nozzles. It may be self-propelled, tractor-mounted, or trailed. Work lights support boom monitoring, field operation, maintenance, and maneuvering in low light. Accurate spraying depends on maintaining the correct boom position, coverage, speed, and nozzle performance across the field. At night or in poor visibility, lighting can help the operator monitor the boom ends, nozzles, wheel path, obstacles, and headlands. The installation should minimize reflections from the machine and illuminated spray while maintaining broad, even coverage.
