3KG Lightweight LED Arrow Board with Triple Power Supply and 500m Visibility Distance for Road Safety Traffic Control

The LED Arrow Board is a visual directional guidance device designed for road safety scenarios, using red LED arrows as its core to provide clear, long-distance directional guidance for vehicles.

It can be placed independently on roads, mounted on service vehicles for mobile use, or used with Truck-Mounted Attenuators (TMAs) to form an integrated "Cushion + Warning" safety solution, meeting the needs of both mobile operations and fixed-site construction.

Weighing only 3KG, it can be quickly carried and deployed by a single person. The arrow direction is clearly identifiable from over 500 meters away, giving approaching vehicles ample reaction time. The triple power supply of solar, DC, and AC ensures 24/7 continuous operation even in remote areas without power. The full aluminum body is waterproof and rust-proof, operating reliably in rain, snow, and fog. Three modes — steady, fading, and flashing — can be flexibly switched according to day/night periods and traffic conditions, reducing driver visual fatigue and improving guidance efficiency.

• Lightweight & Portable: Weighs only 3KG; one person can carry and deploy it without lifting equipment.
• Three Flashing Modes: Steady, Fading, and Flashing modes can be switched flexibly according to day/night or traffic conditions, reducing driver fatigue.
• Triple Power Supply: Solar, DC, and AC options; charges automatically on sunny days and can be externally powered on rainy days for 24/7 uninterrupted operation.
• Full Aluminum Body: One-piece bent aluminum with anti-rust electrostatic spraying; waterproof, rust-proof, and fog-resistant, operating stably in rain, snow, and fog.
• Multi-Scenario Adaptability: Can be placed independently on roads, mounted on service vehicles, or used with TMAs to form a "Cushion + Warning" solution.
• High Brightness & Long-Distance Visibility: Light guide plate design makes the arrow direction clearly identifiable from over 500 meters away, giving approaching vehicles ample reaction time.

• Road Construction: Early warning ahead of construction sites, guiding vehicles to change lanes, slow down, or detour, ensuring safe passage through the work zone.
• Traffic Control: Directional guidance and traffic flow management at temporary control sections and accident scenes, quickly establishing orderly traffic.
• Low-Visibility Areas: High-brightness red arrow warnings under poor visibility conditions such as rain, snow, fog, and at night, compensating for limited visibility.
• Mobile Operations: Mounted on service vehicles for mobile use, providing accompanying warnings for maintenance, patrol, emergency rescue, and other mobile scenarios.
• Fixed-Site Construction: Placed independently on roads for long-term directional guidance and safety warnings at fixed construction sites.
• Integrated Safety Solution: Used with Truck-Mounted Attenuators (TMAs) to form an integrated "Cushion + Warning" protection, suitable for high-risk operations such as highways and urban expressways.
