One-Person Setup LED Arrow Board with Aluminum Alloy Plate and Over 500 Meters Visibility for Road Work Safety

The LED Arrow Board is a visual directional guidance device engineered for road work safety. Its one-piece bent aluminum alloy plate body weighs only 3KG, enabling rapid one-person deployment. High-brightness red LEDs actively illuminate and remain clearly identifiable from over 500 meters away, with three manually switchable modes: Steady, Fading, and Flashing. A multi-path power supply — DC, AC, and solar — combined with a built-in battery ensures 24/7 operation. The full aluminum body is rust-proof, waterproof, and fog-resistant, operating stably across a wide temperature range of -20℃ to +60℃. It supports four installation methods and can be paired with TMAs to form an integrated protection solution.

• Advantage 1: Active Illumination — Warnings No Longer Rely on Headlights

  High-brightness red LEDs actively illuminate rather than passively reflect, remaining striking in rain, fog, at night, and under backlight conditions. A light guide plate with high-transmittance lens ensures saturated, uniform arrow colors, with the arrow direction clearly identifiable from over 500 meters away — allowing approaching vehicles to anticipate and change lanes before reaching the work zone.

• Advantage 2: Lightweight Body — Deployment No Longer Relies on Manpower

  Formed from one-piece bent aluminum alloy plate, the structure is sturdy and deformation-resistant while weighing only 3KG. With a portable handle, one person can carry and position it in seconds — no lifting equipment or multi-person coordination required. Temporary deployment and emergency dispatch both respond quickly.

• Advantage 3: Multi-Path Power Supply — Operation No Longer Limited by Power Sources

  Integrates DC, AC, and solar power with a built-in high-performance battery for storage. Connect to mains power where available, rely on solar where not, and use DC power for vehicle-mounted scenarios — ensuring 24/7 continuous operation even in remote areas without power, so warnings are never interrupted by a power failure.

• Advantage 4: Full Aluminum Protection — Equipment No Longer Fears the Weather

  The aluminum shell undergoes anti-rust electrostatic spraying, making it waterproof, rust-proof, and fog-resistant. Core circuits and the battery box are independently sealed, forming double protection with the shell for stable operation across a wide temperature range of -20℃ to +60℃ — remaining reliable in rain, snow, and fog.

• Advantage 5: Three Switchable Modes — Warnings No Longer One-Size-Fits-All

  Steady mode suits daytime or smooth traffic; flashing mode suits nighttime or complex road conditions; fading mode suits transitional sections requiring gentle warnings. Switch manually via the body panel to match warning intensity to work periods and traffic conditions, balancing effectiveness with visual comfort.

• Advantage 6: Multiple Installations — No Longer Limited to a Single Scenario

  Four installation methods — wall-mounted, hanging, independent placement, and vehicle-mounted — adapt to fixed construction sites, temporary deployment, and mobile operations. Used with Truck-Mounted Attenuators (TMAs), it upgrades from single-point warning to integrated "Cushion + Warning" protection.

• Construction Sections: Deployed ahead of work zones so approaching vehicles have enough distance to change lanes and slow down.
• Temporary Road Closures and Accident Scenes: Quickly establishes orderly traffic flow and guides vehicles to detour.
• Rain, Snow, Fog, and Night: Active illumination compensates for limited visibility, remaining identifiable from a distance.
• Mobile Operations with Vehicles: Mounted on maintenance, patrol, and rescue vehicles — warning wherever the work goes.
• Fixed Construction Sites: Placed independently on roads for long-term duty at fixed locations.
• High-Risk Highway Operations: Used with TMAs so cushioning and warning work in tandem.
