RECTANGULAR RAPID FLASHING BEACONS
“LIGHT BAR” & SYSTEMS
The Federal Highway Administration (FHWA) has granted interim approval for optional use of Rectangular Rapid Flashing Beacons (RRFB) to supplement standard pedestrian and school crosswalks signs at uncontrolled approaches, functioning solely as a warning beacon.
ELTEC’s Rectangular Rapid Flashing Beacon complies with the FHWA’s approval. According to the FHWA’s data, the RRFB had very high rates of motorist “yield to pedestrians” compliance (approx. 80%-100%) compared to standard beacons (15%-20% range).
The RRFB is a rectangular shaped, high intensity LED, which flashes in a wig-wag (three/two) flickering pattern. The alternating strobe pattern provides direct, ultra bright concentration as well as wide-angle intensity.
ELTEC has designed two styles of light bars for roads with and without medians or for one-way streets. The lights are recessed to minimize vandalism. The light bars standard finishes are either Federal Yellow or brushed aluminum. Optional powered coated custom colors are also available.
One-sided/2LED’s used on crossings with a median; mounts to a standard 4.5” O.D. pole.
Two-sided/5LED’s used with two-lane pedestrian crossings; mounts to either a 2.5” or 4.5” O.D. pole. The end-mounted LED verifies system initiation to pedestrians.

Both RRFB light bars can be retrofitted to existing (poles) pedestrian crossings using round flashing beacons or integrated in new systems. They work with either DC (solar) or AC systems that incorporate a 120VAC to 12VDC converter. All solar systems are sized for optimal performance to ensure that light intensity always meets ITE requirements.
The lights can be activated by push button or by a passive device such as a microwave detector. Units are typically connected by radio for wireless operation, eliminating the need to trench or bore. The radios have 65,000 different addresses to ensure that only the desired units operate from a signal. Units may be hardwired if desired.
