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

Designed for municipal intersections, county highways, school approach zones, industrial roads, and private developments. The solar powered flashing LED stop ahead sign (W3-1) improves driver awareness before stop-controlled intersections, helping reduce sudden braking, rear-end collisions, and high-speed approach risks.

This high visibility solar stop ahead warning sign uses bright flashing amber LED perimeter lighting and premium reflective sheeting to deliver strong daytime and nighttime recognition in demanding roadway environments.
