Now Available: All MUTCD W-Series LED Warning Signs (W-Series)
Mike MadiaWe just made it easier for public works crews, traffic engineers, and safety managers to improve dangerous roads and crossings.
Alert Lighting Co. now manufactures solar-powered, MUTCD-compliant LED warning signs for every W-Series legend — all in the standard 30x30" diamond shape.
From deer crossings to sharp curve warnings, and from railroad advance signs to stop ahead LEDs, any official W-code can now be ordered online as a high-visibility, flashing LED sign.
✅ What Are W-Series Signs?
The "W" in W-Series stands for “Warning.” These diamond-shaped MUTCD signs alert drivers to upcoming hazards, road conditions, crossings, curves, and more. They’re critical for driver awareness and roadway safety.
Alert Lighting now offers any W-Series sign with a solar-powered LED border, including:
- W1-1: Curve Ahead Sign
- W1-2: Reverse Curve Warning
- W3-1: Stop Ahead Sign with Flashing LEDs
- W10-1: Railroad Advance Warning Sign
- W11-3: Deer Crossing Sign

- W5-1: Narrow Bridge
- W12-2: Low Clearance Sign
- And more: W4, W6, W7, W8, W9, W13, W16, W25…
These are built to the same standard as our best-selling W11-2 Pedestrian Crossing Sign — using 3M Diamond Grade reflective sheeting, Cree LEDs, weatherproof aluminum housing, and solar-powered battery systems.
