Definition & Explanation

Pick by Light reduces picking errors and increases warehouse throughput by guiding operators directly to the correct shelf position through illuminated indicators. When an order is triggered, a light display at the relevant bin shows the item and quantity to pick; the operator confirms by pressing a button, extinguishing the signal. The warehouse management system (WMS) controls the lights in real time, automatically updates stock levels, and generates performance data for ongoing process optimization. The technology is particularly effective in high-velocity picking zones with a defined article range, such as pharmaceutical or electronics distribution. Unlike Pick by Voice, Pick by Light requires fixed hardware at every pick location, which raises upfront investment but delivers advantages in compact warehouse layouts with short travel distances.
