What is Pick To Light?
Pick To Light, also known as DPS (Digital Picking System), is a semi-automated solution in smart warehouse management, designed to optimize speed and accuracy during the order fulfillment process. This system operates based on a combination of computer software and LED indicator modules to pinpoint the exact location of the items to be picked.
When a retrieval request is made, the light at the product's storage location will illuminate or flash, while simultaneously displaying the required quantity. The operator simply moves to the lit rack, picks the displayed quantity, and confirms the action. Consequently, Pick To Light helps shorten search times, minimizes picking errors, and allows both new and experienced staff to operate quickly and easily.
Pick To Light technology solution for smart warehouses
Pick To Light offers flexible integration with other management systems such as WMS (Warehouse Management System), ERP (Enterprise Resource Planning), or supply chain management platforms. This allows businesses to synchronize data, optimize logistics processes, save costs, and enhance the customer experience.
Advantages and Disadvantages of Pick To Light Solutions
Advantages of Pick To Light
Among the semi-automated solutions supporting warehouse picking activities, Pick To Light is highly regarded for its ability to integrate several outstanding benefits:
- High Processing Speed: The system can significantly shorten picking time, performing up to 2.5 times faster than paper-based list picking and twice as fast as handheld picking.
- Reduced Dependence on Employee Experience: Both novices and veterans can operate easily thanks to intuitive visual light signals.
- Reduced Work Pressure: Employees do not need to memorize SKU codes or specific locations within the warehouse.
- Simplified Workflow: Simply follow the light guidance without the need for complex decision-making during operation.
- Hands-Free Operation: Employees do not have to carry scanners or supporting devices, making the picking process more ergonomic and streamlined.
Specially structured Pick To Light - a key part of warehouse digital transformation
Thanks to these advantages, Pick To Light is considered by many businesses as an effective picking support solution, suitable for enhancing productivity in warehouse management.
Disadvantages of Pick To Light
Despite its strengths, the Pick To Light system has some limitations that businesses should consider:
- Human Error: Since manual intervention is still required, picking the wrong quantity or location while still hitting the confirmation button can occur.
- Semi-Automated Nature: Similar to other methods like handheld picking, voice picking, or AR picking, Pick To Light does not entirely eliminate operator-induced errors.
- Not Always Suitable: For certain warehouse models or business scales, investing in Pick To Light may not yield as much value as other picking methods.
Despite these drawbacks, Pick To Light remains one of the optimal picking solutions of the 21st century. This is due to the balance between cost, efficiency, and implementability, helping businesses improve productivity while reducing operational errors—particularly suitable for e-commerce, logistics, and manufacturing sectors with high order volumes.
Why is Pick To Light the Future Trend for Smart Factories?
With its ability to accelerate picking speeds, reduce reliance on personnel experience, and easily integrate with ERP and WMS systems, Pick To Light is becoming an inevitable trend in the smart factory model.

Pick To Light in Developed Nations
In technology-pioneering markets such as the US, Europe, China, and Singapore, Pick To Light continues to be maintained and developed strongly. The question is: "Why do countries famous for advanced automation inventions continue to use Pick To Light?". The answer lies in its durability, flexibility, and cost optimization. Pick To Light still meets the needs of modern warehouse management, especially in industries requiring high-speed order processing.
In markets like Southeast Asia, India, Africa, and Latin America, businesses often worry about the investment costs for automation. Compared to fully automated picking systems, which require complex calculations and high capital expenditure, Pick To Light emerges as a balanced solution:
-
Significantly lower investment cost compared to fully automated systems.
-
Easy to deploy without requiring drastic changes to existing processes.
-
High scalability, allowing expansion based on annual production needs.
Process Improvement and Accuracy Enhancement
The benefits of Pick To Light go beyond being "faster" or "more accurate"—concepts that can be abstract without hands-on experience. In practice, the system provides concrete value:
-
Process Control Support: Every picking action by an employee is recorded, monitored, and easily traceable when needed.
-
Maintaining Employee Focus: Thanks to guided lighting and immediate confirmation on the module, operational staff can work more accurately during repetitive tasks.
-
Increased Transparency: Picking data can connect to management systems, helping leaders track performance and optimize resources.
Trends in Using Pick To Light in Vietnam
Vietnam is becoming a destination for the global manufacturing shift. As demand in the apparel, trade, and industrial manufacturing sectors rises, businesses face the challenge of upgrading productivity to meet market competition. In this context, Pick To Light is the most balanced and suitable solution for many factory models.
The Current State of Manufacturing in Vietnam
Most picking activities still rely heavily on humans and the experience of skilled workers. However, when demand spikes, simply increasing manpower soon hits the ceiling of the "Law of Diminishing Returns," where adding staff no longer brings efficiency and even increases management costs.
While fully robotic automation may be a long-term goal, Pick To Light stands out for its ease of deployment, reasonable investment cost, safety, immediate results, simple maintenance, and high durability. It also maintains a "human-centric" approach, avoiding the pressure of mass personnel cuts.
Pick To Light has become an ideal semi-automated solution, improving productivity while maintaining stability in the production environment. This is particularly important in Vietnam, where many FDI enterprises must comply with local job creation commitments.
With low initial investment, flexible deployment, and almost immediate results, Pick To Light opens opportunities for Vietnamese businesses to develop sustainably in the smart factory trend. With experience implementing large automation projects in Vietnam, Intech Robotics is proud to be a pioneer in providing modern, durable Pick To Light solutions that easily integrate with WMS, ERP, or supply chain systems. We are committed to providing businesses with cost-optimized solutions, outstanding efficiency, and dedicated support, helping you stay ready for a breakthrough.
