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.
