Formula 1 flags are the sport's universal language. Marshals wave them at the track. Race control displays them on screens. And now, with Race RGB, they light up your room.
But what do each of these flags actually mean? And how does Race RGB translate them into immersive light patterns? Let's break it down.
Red flag
Session stopped
The red flag means the session has been stopped. This happens when track conditions become unsafe - usually due to a crash, weather, or debris on track. All cars must slow down and return to the pit lane.
How Race RGB handles it:
Your lights flash red in a pulsing pattern, matching the urgency of the moment. The intensity ramps up when a red flag is shown, then settles into a steady flash for the duration of the stoppage.
Yellow flag
Caution / danger ahead
Yellow flags indicate caution. There are two types:
Single yellow
Slow down. Overtaking is prohibited. Usually means there's a car stopped on track or marshals on track.
Double yellow
Danger ahead. Drivers must be prepared to stop. This is shown when there's a crash, debris, or significant hazard on or near the track.
How Race RGB handles it:
Single yellow = gentle yellow pulse. Double yellow = intense yellow flash. Your lights automatically adjust based on the flag severity, so you feel the difference between "car stopped" and "crash ahead."
Green flag
Racing conditions
Green flag means racing conditions. It's shown at the start of every session and when the race resumes after a safety car or red flag period.
How Race RGB handles it:
Your lights pulse green when the green flag is shown. It's especially dramatic after a safety car period - everything goes from yellow to green, and you can literally feel the race restart in your space.
Other events Race RGB tracks
Safety car
SC boards appear on track when the safety car is deployed.
Race RGB: Continuous yellow pulse
Virtual Safety Car (VSC)
Virtual safety car deployed when track conditions require caution but no physical safety car.
Race RGB: Pulsing yellow
VSC ending
Virtual Safety Car period ending.
Race RGB: Pulsing yellow as VSC ends
Chequered flag
Session complete. Race finished.
Race RGB: White flashing pattern
Fastest lap
When a driver sets the fastest lap of the race.
Race RGB: Purple flash, then returns to previous state
How Race RGB translates flags to lights
Race RGB pulls real-time flag data - the same data F1 uses for their official timing screens. When a flag is shown at the track, it appears in the API within seconds.
The system processes each flag and translates it into a light pattern:
- •Red flags trigger an intense red flash pattern
- •Yellow flags create a pulsing yellow effect, with intensity based on single vs. double yellow
- •Green flags pulse green, especially dramatic after restarts
- •Safety Car and VSC trigger continuous yellow pulsing
- •Chequered flag flashes white when the session ends
- •Fastest lap creates a purple flash before returning to previous state
All of this happens in real-time, with your calibrated delay ensuring the lights match what you're seeing on your TV or stream. It's like having a visual translation of race control in your room.
Why this matters
Understanding flags is one thing. Feeling them in your space is another. When you experience a red flag through your lights - when everything goes from racing green to urgent red - you feel the tension in a way that's impossible through a screen alone.
It's the difference between watching F1 and living it. And that's why I built Race RGB.
