Frequently Asked Questions
Q1: What does 3500mm refer to in this product?
3500mm (3.5 meters) refers to the length of the retractable light strip inside the light box. The strip can be pulled out to expand the warning range and fully retracted into the box for easy storage and transport.
Q2: What is the "dynamic flashing" function?
Dynamic flashing means the LED lights change in a specific sequence and frequency (e.g., sequential arrow lighting, rapid flashing), creating a flowing or blinking visual effect that captures driver attention more effectively than static lights.
Q3: What is the purpose of the retractable light strip?
When pulled out, the light strip creates a linear warning barrier to delineate hazard zones and guide traffic around the area - offering a much larger warning range than traditional fixed warning signs.
Q4: What are the main applications for this product?
It is mainly used in road construction, lane closures, accident scenes, maintenance work, and temporary breakdown parking - any scenario requiring an expanded warning range or traffic guidance.
Q5: Why is the retractable design used?
The retractable design balances large-area warning and portable storage. Pull out the 3.5m strip for extended warning; retract it back into the box to save space - easily fits in a vehicle trunk.
Q6: How do Chinese factories ensure product quality?
Factories implement strict quality control at every stage - from LED chips and retractable mechanisms to final assembly and aging tests - ensuring reliable and durable performance.
Q7: What is the difference between a dynamic flashing arrow board and a regular warning sign?
Regular warning signs are passive reflective or static lights and are often overlooked. A dynamic flashing arrow board uses moving arrows, high-frequency flashing, and an extended light strip to be far more eye-catching - especially at night or in complex road conditions.
Q8: How is the light strip secured when extended?
Once pulled out, the light strip can be placed directly on the ground.
