Waterproof Red Lamp 3kg LED Arrow Board
This high-performance LED Arrow Board is specifically designed for road construction, traffic control, and emergency rescue scenarios. With a lightweight design weighing only 3KG, it enables easy carrying and deployment by a single person, significantly improving on-site emergency response efficiency.
The arrow board features versatile applications - it can be used independently on roads, integrated with our complementary products, or installed on the rear of road maintenance vehicles for mobile operations.
The light guide arrow consists of 8 red waterproof plastic sections equipped with high-intensity LED lamp beads. In low visibility conditions, the activated red lights provide exceptional visibility for traffic guidance.

Frequently Asked Questions
What is the main function of the LED Arrow Board?
Primarily used for road construction, traffic accident sites, or closed sections. It guides vehicles to detour, change lanes, or slow down through arrow light direction indication, ensuring safety of personnel and equipment in work zones.
Why use an arrow board in construction areas instead of ordinary warning signs?
Ordinary warning signs only reflect light passively with limited effectiveness in low visibility. Arrow boards use active LED lighting with dynamic flashing modes, making them more likely to catch driver attention and provide better early warning.
Can it work on cloudy or rainy days with solar power?
Yes. The solar panel charges the built-in battery on sunny days. The stored power supports continuous work for 8-10 hours on rainy days (depending on mode). During prolonged rainy periods, you can switch to DC or AC power.
What scenarios are the three light modes suitable for?
Steady Mode: Suitable for daytime with acceptable visibility or scenes requiring continuous warnings.
Fading Mode: Slowly changes brightness, soft and eye-catching. Ideal for nighttime use to reduce glare.
Flashing Mode: Rapid flashes with strongest penetration. Suitable for rainy/foggy weather or emergency danger zones.
How do I switch light modes and power supply modes?
A remote control is included for switching light modes from a distance. Power supply modes are switched by plugging in different power cords or toggling switches (solar mode is automatic).
Is installation complicated? Does it require professional operation?
Very simple. For independent placement, no installation needed—just place on the road. For vehicle mounting, simply secure the bracket with screws and connect the power cord. Ordinary workers can handle it.
How to clean and maintain the product?
Regularly wipe the solar panel and LED surface with a soft cloth to maintain cleanliness. If unused for extended periods, charge every 3 months to protect battery life. Check power cords for damage periodically.
Can the arrow board display other patterns or text?
The standard product features red arrow indication. For custom patterns (such as X symbols or text), special customization is required. Please consult our sales representative.
