Rectangular Rapid Flashing Beacon (RRFB)
Rectangular Rapid Flashing Beacon Image
A RRFB is an amber-colored flashing light mounted on a pole under a pedestrian crossing sign. It is activated by a pedestrian pushing a button on the pole before entering a crosswalk or making a mid-block crossing. Pedestrians are expected to wait until drivers yield before entering the crosswalk. The lights are set to allow time for vehicles to yield, and they continue to flash as pedestrians cross the roadway.

When the beacon is activated, its yellow lights begin flashing and it catches drivers’ attention. Motorists are required by Texas law to stop for pedestrians even if the beacons are not lit. Pedestrians should make sure cars are stopped before stepping into the street and be aware that motorists may not see them or obey the law.
