Chevron Sign Flashing LED Ring – Left

Part Number: M75-Rxxxx-BA1L

Summary

The Chevron Sign Flashing LED Ring – Left outlines the perimeter of a standard left chevron warning sign with high-intensity amber LEDs to guide drivers through curves and ramps. Designed to retrofit existing MUTCD-compliant chevron signs, this LED ring creates a dynamic, highly visible indication of horizontal curves, especially at night and in adverse weather. Fully sealed electronics, rugged construction, and 12 VDC operation make it ideal for long-term deployment as part of TraffiCalm curve warning systems.
