Solar-Powered Flashing LED Stop Ahead Warning Sign (W3-1) – MUTCD Compliant

Made for municipal intersections, county highways, school approach routes, industrial sites, and private developments, the Solar-Powered Flashing LED Stop Ahead Sign (W3-1) sharpens driver awareness at stop-controlled intersections, helping cut down on last-second braking, rear-end crashes, and high-speed approach incidents.

Core Advantages

• Sharpens driver awareness approaching stop-controlled intersections
• Strengthens safety on high-speed approaches and intersections with limited visibility
• Lowers the chance of rear-end collisions and abrupt braking
• Runs entirely on solar power — no digging or utility hookup needed
• Built for reliable, low-maintenance use in demanding roadway settings

Superior Visibility

• High-intensity amber LED border lighting delivers bright, even flashing that commands driver attention
• 3M™ Diamond Grade™ Cubed reflective sheeting provides outstanding visibility day and night
• Improves sign recognition from a distance and speeds up driver reaction time
• Well-suited to rural highways, municipal roads, school approaches, and industrial traffic corridors

Dependable Solar Operation

• High-grade 12V lithium battery with a built-in Battery Management System (BMS)
• Stays powered for up to 55 days without sunlight after a full charge*
• High-efficiency solar charging keeps performance steady all year
• Removes the need for trenching, conduit, or utility power

*Actual runtime depends on flash pattern and location.
