STOP TRAFFIC FOR EVERY PEDESTRIAN
Solar Rectangular Rapid Flashing Beacons
High-intensity amber beacons and a battery-free push button in a slim, solar package that installs like a standard sign. MUTCD compliant. No trenching, no grid, no wiring.
MUTCD compliant and FHWA-recognized. Ships ready to mount on new or existing posts, with each unit engineered to run year-round on solar alone, even through overcast weeks.
What is an RRFB?
A Rectangular Rapid Flashing Beacon (RRFB) is a pedestrian-activated warning light installed alongside a crosswalk sign. When a pedestrian presses the button, two amber beacons flash in a rapid, irregular pattern that alerts approaching drivers someone is crossing. An RRFB does not stop traffic the way a signal does. It increases driver awareness at crosswalks that do not otherwise have one, which is why FHWA classifies it as a Proven Safety Countermeasure.
Why it works
A marked crosswalk is easy to miss. The Smart-Flash RRFB adds a rapid, irregular amber flash that only fires when someone is crossing, cutting through headlight glare, wet roads, and busy backgrounds so drivers react sooner.
Why buy the Smart-Flash RRFB?
Installs like a sign.
Universal bracket mounts top or side of a standard pole. Connectors hide inside.
No wiring, no trenching.
All-in-one solar unit: 30 W panel, LiFePO4 battery, and MPPT charger in one plug-and-play package.
Battery-free button.
The included piezoelectric push button powers itself and talks to the beacon over an encrypted 902 MHz link.
Seen day and night.
SAE J595 Class 1 LEDs visible past 1000 ft, with auto-dimming for ambient light.
Built to last outdoors.
IP65 aluminium housing, 100,000-hour LEDs, and a battery rated for roughly 15 years.
MUTCD Compliant.
Ships in the default WW+S pattern. Designed and manufactured in North America.
How it works
The Push Button
- Wireless and battery-free - A piezoelectric actuator generates the power to fire the signal from the press itself, so there is nothing to charge and nothing to swap out.
- No battery, ever - Piezoelectric power means no button cell to source, replace, or send a crew out to change.
- Encrypted and wireless - It talks to the beacon over the same encrypted 902 MHz link, so there is no wiring to run to the button post.
- Included in every system - Ships with the kit, ready to pair, with no separate purchase.
The Beacon
Two rectangular amber beacons do the work of getting drivers to stop. They are bright, MUTCD-ready, and built to survive years of weather and road impact.
- High-intensity amber LEDs - Rated SAE J595 Class 1, visible past approximately 300 m (1000 ft), behind a UV-resistant clear polycarbonate lens that resists yellowing and impact.
- Auto-dimming - A photocell varies brightness with ambient light, so the beacon punches through daylight without glaring at night.
- MUTCD Flash Patterns - WW+S (the default), BLOCK, or 2-5, all at 60 flashes per minute, on demand.
- Smart Onboard Controller - Manages the photocell, flash patterns, encrypted 902 MHz communication (up to approximately 100 m / 300 ft free field), and scheduled activation.
The Battery
- Maintenance-free storage - A LiFePO4 pack sized to keep the system flashing through cloudy stretches and long nights.
- LiFePO4 chemistry - 12.8V, 14Ah, with a life expectancy of roughly 15 years.
- Light and slim - Keeps the all-in-one unit compact and pole-friendly.
- No servicing - No watering, no scheduled swaps, no seasonal servicing.
The Solar Panel
A high-efficiency solar unit keeps everything charged off-grid, so there is no trenching and no utility hookup.
- 30 W monocrystalline - Higher-efficiency cells let the panel stay compact while capturing more energy.
- MPPT charging - The MPPT controller lifts charging efficiency by at least approximately 20 percent over a PWM controller, so more sunlight reaches the battery.
- Universal bracket - Mounts to the top or the side of the pole, with an LED status indicator and a snap-in connector for quick setup.
- Sealed and rugged - IP67 charger rated for -40 to +165 F (-40 to +74 C).

Frequently Asked Questions
Does it need power or wiring?
No. It is a self-contained solar system with an onboard LiFePO4 battery.
Does the button need batteries?
No. It is piezoelectric and battery-free.
Is it MUTCD compliant?
Yes, and it ships with the WW+S pattern as the default.
How is it activated?
On demand. It flashes when a pedestrian presses the button, then stops.
How much do RRFBs reduce pedestrian crashes?
FHWA research shows RRFBs can reduce pedestrian crashes by up to 47 percent (FHWA-SA-21-053).
Where should an RRFB be installed?
At midblock and uncontrolled crosswalks, school zones, multilane roads posted at or below 40 mph, trail crossings, and transit stops.
Can an RRFB be used at a stop sign or traffic signal?
No. FHWA guidance reserves RRFBs for crosswalks not already controlled by a YIELD sign, STOP sign, traffic signal, or pedestrian hybrid beacon.
How long does the battery last?
The LiFePO4 battery has an expected life of roughly 15 years with no scheduled maintenance.
