Pick-to-light warehouse systems for error reduction

Several established warehouse automation providers offer pick-to-light systems that guide pickers to the correct shelf location and display the required quantity. For your problem—errors caused by similar-looking items—I'd prioritize systems with clear visual guidance, pick confirmation, and integration with your warehouse management system (WMS).

What to look for to reduce picking errors

When speaking with vendors, ask whether their system supports:

• SKU-level visual identification: A dedicated light and readable display at each pick location.
• Pick confirmation: Sensors, buttons, or barcode scanning to catch an incorrect pick before the order moves on.
• Similar-item differentiation: Clear SKU or item descriptions, not just a light indicating a shelf.
• WMS integration: Automatic transfer of pick instructions and inventory updates.
• Measured accuracy improvements: Customer case studies showing error rates before and after installation.

My recommendation: Start with Lightning Pick because its published case study directly addresses picking similar-looking product boxes. Compare it with Honeywell if your warehouse has more complex, high-volume workflows.automation.honeywell.com+2

One question that would help narrow this down: Are your pickers selecting small individual items from shelves, full cases, or products stored in bins/totes? The best system depends on that picking method.
