3KG Lightweight LED Arrow Board with Triple Power Supply and 500m Visibility Distance for Road Construction Warning

An LED arrow board for road work safety guidance, with red LEDs actively illuminating and three modes — Steady, Fading, and Flashing. It features an aluminum alloy plate body and is suitable for construction, traffic control, and low-visibility scenarios.

Seeing far, deploying fast, and holding up: clear warning from over 500 meters, 3KG one-person seconds-level deployment, and multi-path power supply with full aluminum protection for all-weather operation.

Red is the universal warning color on roads with strong visual impact. High-brightness LEDs actively illuminate, and with the light guide plate and high-transmittance lens, the color is saturated and uniform — equally striking in rain, fog, and at night.

Use steady mode for daytime smooth traffic, flashing mode for nighttime or complex road conditions, and fading mode for transitional sections. Switch manually via the body panel to match warning intensity to the scenario.

One-piece bending reduces seams for a sturdy, deformation-resistant structure. Lightweight design keeps the total weight at only 3KG. Anti-rust electrostatic spraying makes it waterproof, rust-proof, and fog-resistant — not easily damaged in long-term outdoor use.

Three options: DC, AC, and solar, with a built-in high-performance battery. Connect to mains power where available; rely on solar where not — ensuring 24/7 continuous operation.

Yes. The aluminum shell and independently sealed circuit compartment form double protection, operating across a wide temperature range of -20℃~+60℃, stable and reliable in rain, snow, and fog.

Four methods: wall-mounted, hanging, independent placement, and vehicle-mounted. Used with Truck-Mounted Attenuators (TMAs), it forms integrated "Cushion + Warning" protection.
