The wheel is great and everything but I really want the LEDs to work in LFS!
Can somebody help me please?

the game does not have support for them...maybe if you search for an insim app, or try to make one yourself

I already saw people using logitech G27 LEDs on lfs..

And what is a insim app?

try this out

Where exactly should I look in?

At the moment the only way to make the RPM LEDs working is through an InSim app, but someone will have to create one in the first place. I've taken a look at the API so I might give it a try; it doesn't look like a big deal. But I make no promises, after all, I don't have G27 so I'd have no way of testing my idea

You can come to my house to test it if you want
lol, thanks anyway, if you do get to test it and succeed, pm me alright?
