Pick-to-Light systems are mounted technology on pallet rack, shelving, etc. to help pickers find the right items to fulfill an order. What makes this type of system so valuable is its simplicity. Like in a Put-to-Light system, the operator will scan the order code and the locations with the items needed for the order will illuminate until the order is fulfilled.
Pick-to-Light is normally applied in Zone Picking, a picking process where each picker works in a designated area to reduce foot traffic and travel time. Once the picker finishes their picks in their respective zone, the order is then passed on to the next picker in the queue where they will do the same. This assembly line-like method keeps your distribution center moving and able to get more orders out in a shorter amount of time.
