Where is Pick-to-Light used?

Pick-to-Light is very versatile and is used wherever simple information is to be displayed directly at storage compartments or at machines. The operator can make the appropriate entries via various keys on the Pick-to-Light compartment displays.

eCommerce: Picking and replenishment in the dispatch warehouse

In a shipping warehouse, the Pick by Light is mostly used for picking the A or B items. This fast picking method brings enormous advantages for performance and quality. The use of a conveyor system in combination with a material flow system further optimizes the overall system.

When using the conveyor technology, the shipping cartons automatically travel to the individual picking zones. The order is not activated until after ejection and the appropriate displays light up. The strong LED signals the position from a great distance. Whereby the displays show the removal quantity directly. Afterwards, the employee acknowledges the removal with a button directly at the display.

If the stock level at the storage compartment does not match, the employee can enter a message for a shortage directly at the display.

In addition to picking, the Pick-to-Light system is also used very successfully to support replenishment. Simple "Put-to-Light" displays are mounted on the individual replenishment channels in a shelf. When the replenishment orders are activated, the corresponding display lights up. The employee is guided directly to the correct storage compartment. Acknowledgement takes place via the button on the display or with the aid of a scanner.

Automotive: Supermarket sequencing of shopping carts and JIT racks

Pick by Light plays a very large and decisive role in the preparation of assembly as shopping baskets and JIT racks in an automotive plant. The large number of models and variants makes direct storage of the car parts directly on the assembly line impossible for reasons of space. For this reason, the car parts are also stored and "retrieved" in neighbouring halls or even at remote service providers. These storage areas are often called supermarkets (SuMA).

The assembly line of an automotive plant must be supplied 100% without errors and at the right time.

The preparation of car parts in supermarkets is called sequencing. We will soon publish a separate article about sequencing in automotive production itself. Stay tuned ...

Our systems and the LUCA-Server are specially developed for customers with high quality requirements and are perfectly suited for trouble-free continuous use. The Quick-Click-System allows a quick and easy conversion of the system. Thus, the requirements for changing car parts (alternative parts) are met without any problems.

Production: assembly stations, set formation and machine placement

In production, the system can be used in a particularly versatile manner. Not only one, but several product variants are often assembled at an assembly table or assembly workstation. The components are usually provided at the assembly table in small or larger containers and cartons. A large number of product variants, as well as similar and confusable components, can lead to problems with quality and performance. For this, the Pick by Light can be used very well as an aid.

After activating the orders, the corresponding displays light up directly on the components. The entire assembly process is controlled by an existing system or by our LUCA-Server . Not only the access to the components is important here, but also the correct sequence of assembly. It is very important that the system supports the employee and corrects his possible mistakes if possible (PokaYoke). Additional sensors on the displays monitor the activities and immediately report errors in the event of any mix-ups.

Pick by Light can also be used very well for set formation and machine placement. However, these applications are very versatile and require precise process planning. We will be happy to answer any questions you may have.


The Pick by Light systems can be used in many industries. However, the objectives are different in each industry. All of these tasks can be solved with our flexible LUCA-Server . The most important thing is a correct planning. We are happy to support you here. Contact us and learn more about this.
