Yield Sign Flashing LED Ring (R1-2)

Part Number: M75-R3030-WR49 / M75-R3636-WR49 / M75-R4848-WR49

MUTCD Sign Rings: If your controller is running firmware 401N or >, adjust brightness from 100% to 60%. Failure to do so will result in higher power draw and solar systems may fail.

Summary

The Yield Sign Flashing LED Ring enhances standard R1-2 Yield signs by outlining the triangular border with high-intensity red LEDs. Designed to increase attention and compliance at intersections, merges, and two-way stop locations, this LED perimeter system provides exceptional visibility and weather-resistant performance. The ring operates from 12 VDC and is compatible with TraffiCalm controller-based triggering and scheduling.
