Single leds are not supported directly to simhub, you can use a single ws2812b RGB led like this : https://www.amazon.com/ALITOVE-100pcs-WS2812B-Addressable-Module/dp/B00P2GQUYCThank you. I have another question, I would use a bottom box with led on engine start button.
How i can read the engine state to led on/off?
I would use this only for rbr.
Thank you for your time
To detect engine stall I personally use a simple formula (you can use formulas in the SimHub leds mappings):
if([DataCorePlugin.GameData.NewData.Rpms] ==0 ,1,0)
This tells to output "1" when the engine rpm is equals to 0
Then to use it on leds :
