NexFLAG
LED race flags for karting circuits
NexFLAG shows track flags on LED displays installed at marshal posts. The flag changes with a single press on the remote control, and every change is time-stamped.

On the track
Every post shows the right flag
Marshals stay in control of their post. Race control keeps an overview.
5-button remote control
At the marshal post, a single press displays the required flag.
Track flags
Green, yellow, red, blue, chequered, black, black-and-orange: the flags appear in colour on a single LED panel.
Centralised control
Control the flags at every post on the circuit from the web interface.
Time-stamped log
Every flag change is time-stamped and recorded. You can review how a session unfolded to analyse it.
Trackside
An illuminated colour flag at every post
The 96 × 64 pixel RGB LED display reproduces the flag in colour. Its IP65 enclosure is built for trackside use, and mains or battery power adapts to the location of each post.
- 2.4 GHz radio link between the Central Unit and the posts
- Range up to 1,000 m in open field
- No network cable to run along the track

How it works
From marshal post to session log
Install a display at each post
Wall, pole or suspended mounting, facing the track.
Connect the Central Unit
It links the posts by radio and centralises flag changes.
Display the flag
The marshal presses the remote control and the flag appears at their post.
Check the log
Every change is time-stamped, so you can reconstruct the session afterwards.
Frequently asked questions
Is NexFLAG approved for competition?
NexFLAG does not currently hold federation approval. If your circuit hosts official events, contact us so we can review your requirements before any project.
Can the posts run on battery?
Yes. The display comes in a mains or battery version. We advise you based on the location of each post.
Do cables need to be run between the posts?
No network cable: the Central Unit communicates with the displays over 2.4 GHz radio frequency, up to 1,000 m in open field.
Can we see NexFLAG in operation before buying?
Yes. We organise a demonstration at your circuit or by video call.
