White LEDs


Summary
The Speed Limit Sign Flashing LED Ring enhances existing or new regulatory R2-1 Speed Limit signs with high-visibility perimeter illumination. White LEDs arranged around the border of the sign significantly increase driver awareness, especially in adverse conditions. The LED Ring operates on 12 VDC, with options for radar-triggered flashing when vehicles exceed the posted speed, scheduled operation, or continuous flashing.
