Fast Deployment Versatile Durable LED Arrow Board and Flashing Arrow Board for Road Work Sites

High-brightness red LED beads actively illuminate rather than relying on headlight reflection, remaining striking in rain, fog, and at night. The light guide plate design with high-transmittance lens ensures saturated and uniform arrow colors, with the arrow direction clearly identifiable from over 500 meters away, giving approaching vehicles ample time to anticipate and change lanes.

The main body is formed from a single aluminum alloy plate through one-piece bending, reducing seams and welding weak points for a sturdy, deformation-resistant structure. Aluminum alloy has low density and high strength, keeping the total weight at 3KG for one-person carrying and deployment. The surface undergoes anti-rust electrostatic spraying, making it waterproof, rust-proof, and fog-resistant — not easily fading or rusting during long-term outdoor use.

Steady mode provides continuous and stable illumination, suitable for daytime or smooth traffic. Flashing mode offers dynamic alerts, suitable for nighttime or complex road conditions. Fading mode features gradual brightness changes, suitable for transitional sections requiring gentle warnings. All are switched manually via the body control panel, allowing flexible selection according to work periods and traffic conditions.

Supports multiple power options — DC, AC, and solar — with a built-in high-performance battery for storage. AC power can be used where mains electricity is available; DC power suits vehicle-mounted or field scenarios; solar charging works automatically on sunny days, ensuring 24/7 uninterrupted operation.

The core circuits and battery box use an independent sealed design, effectively isolated from the external environment to prevent moisture and dust intrusion, forming double protection with the aluminum shell for stable operation across a wide temperature range of -20℃ to +60℃.

Supports four installation methods — wall-mounted, hanging, independent placement, and vehicle-mounted — adaptable to fixed construction sites, temporary deployment, and mobile operations. Used with Truck-Mounted Attenuators (TMAs), it forms an integrated "Cushion + Warning" protection solution.
