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

High-brightness red LEDs actively illuminate without relying on headlight reflection, remaining striking in rain, fog, and at night. The light guide plate with high-transmittance lens ensures saturated and uniform arrow colors, with the arrow direction clearly identifiable from over 500 meters away. Fast-moving vehicles can learn about the work zone ahead in advance and calmly change lanes or slow down, reducing rear-end and intrusion risks at the source.

The main body is formed from a single aluminum alloy plate through one-piece bending — sturdy and deformation-resistant while achieving lightweight construction at only 3KG. With a portable handle, one person can carry and position it in seconds — no lifting equipment or multi-person coordination needed, establishing safety protection ahead of traffic flow.

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 control panel according to work periods and traffic conditions, balancing warning intensity with driver visual comfort.

Supports multiple power options — DC, AC, and solar — with a built-in high-performance battery for storage. Connect to AC power where mains electricity is available; use DC power for vehicle-mounted or field scenarios; solar charging works automatically on sunny days — ensuring 24/7 uninterrupted operation, even in remote areas without power.

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

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, upgrading from single-point warning to systematic safety assurance.
