What are telemetry LEDs?

Telemetry LEDs are the addressable lights on sim racing hardware that show live data from your sim. On a DDU or a high end wheel they sit in three runs:

• A centre strip, the rev bar, showing engine revs and your shift point
• A left side and a right side, carrying everything else: flags, the proximity spotter, brake pressure, pit lane, ERS and low fuel

DNR describes that layout as X-N-X, where N is the number of LEDs across the centre. That is a description of your hardware, not a file to go and find. One RPM profile serves every device, and you tell the plugin your centre width on the RPM Telemetry page. It fits the rev bar and the car's shift points to whatever you set.

Every LED device keeps its own settings, so a wheel, a DDU and a button box can each run telemetry and each do a different job.
