What is an RRFB?

Rectangular Rapid Flashing Beacons (RRFBs) are installed at crosswalks to increase bicycle and pedestrian visibility. RRFBs are often placed at school crossings and locations with high crossing demand.

RRFBs consist of two rectangular yellow light bars, which flash in a vibrant strobe pattern when the push button is pressed. The activation of the RRFB alerts approaching drivers that there is someone using the crosswalk.
