Pick a flag
LMU Hue Flags is a Windows app that syncs your Philips Hue lights live with the race flags in Le Mans Ultimate. Your room reacts to every flag on track, for a whole new level of immersion. Keep scrolling and set up your lights yourself.
The desktop app
Take the colour you like: a preset for the quick way, or a hex value when you have something specific in mind.
Solid for calm signals, blinking for urgent ones. Number of flashes, duration and blink speed are yours to set per flag.
Whether one light shows every flag or each flag gets its own: you decide per event which lights come on.
Flags and signals
Danger ahead
LMU only reports yellow for a whole sector. That is why many tools show yellow as soon as anything happens anywhere in the sector, even when the crash is long behind you. LMU Hue Flags looks for the crash itself and checks how far away from you it is. Only when it is within 500 m ahead of you do your lights turn yellow, and they stay yellow until you are past it.
Race start
In LMU, green only shows at the moment the race starts. Your lights flash green briefly and then go out again.
Faster car right behind you
When a faster car closes to within a second, LMU shows blue, and so do your lights. In a multiclass race you know straight away when a Hypercar wants to get past.
Pit lane
In the pit lane the limiter has to be on, or you get a penalty. As soon as you press it, the room lights up in your pit limiter colour, and you can tell from the corner of your eye that it really is on.
Fastest lap in your class
Cross the line having just set the fastest lap in your class, and the room flashes in your fastest lap colour. That way you celebrate the best time without taking your eyes off the track.
Final straight of the last lap
Not for the whole last lap, only once you reach the final straight. Your lights flash as you cross the line.

Behind the scenes
There is a car stopped around the next corner. Many tools then show yellow for the whole sector, even when the crash is long behind you. LMU Hue Flags takes a closer look.

Le Mans Ultimate
The game keeps writing flags, positions and the speed of every car to its Shared Memory. It only reports yellow for a whole sector.
LMU Hue Flags
The app reads along continuously, finds the stopped car and checks the distance. Up to 500 m ahead of you, that turns into yellow, adjustable in the app. Here it is 320 m.
Hue Bridge
The yellow flag goes over your local network to the Bridge.
Your lights
They stay yellow until you are past the crash.
Help
LMU Hue Flags is a Windows app that turns your Philips Hue lights into race flags for Le Mans Ultimate. When the game shows a yellow, blue or green flag, your lights switch to that colour in real time. The pit limiter and a new fastest lap in your class get their own light signal too.
Install LMU Hue Flags on your PC. In the app, enter your Hue Bridge’s IP address, press the round button on the Bridge and click “Connect”. Then start live sync in the app — from now on your lights follow the flags on track. If the lights don’t react, check in Le Mans Ultimate under Settings → Gameplay that “Enable Plugins” is switched on.
A PC with Windows 10 or newer, Le Mans Ultimate, and a Philips Hue Bridge with at least one Hue light on the same network as your PC. Hue lights controlled only via Bluetooth, without a Bridge, are not supported.
No. LMU Hue Flags reads the live data that Le Mans Ultimate itself provides once “Enable Plugins” is switched on — and only reads it. No files are copied into the game folder and nothing in the game is changed.
Yellow flag, green flag, blue flag, checkered flag, the pit limiter and a fastest lap in your car class. For every signal you choose the colour, brightness, solid or blinking light, and which Hue lights join in.
You can try the app for free: connect your Bridge, assign your lights and preview every flag. Live sync with Le Mans Ultimate needs a license: €1.99 per month, €8.99 per year, or €14.99 once for lifetime use.
