In a pick-to-light system, light modules are mounted to storage media (racks, carton flow, shelves, carousels, etc.) in a zone picking operation. Pickers scan a bar code ‘license plate’ on passing totes to activate an order in their zone. Lights illuminate at each SKU required for the order. Usually for fast moving SKUs the lights feature both a location light and a quantity display to guide pickers to the right SKU and number of pieces needed. Pick to light technology is also used in assembly, putaway, and manufacturing operations.
