Just kind of wondering if support for the lights on the G27 steering wheel was removed? Or do I have a problem? I got used to seeing them in my periferal vision. And developed an automatic response to the flash. Either let off the gas or shift. Now without them there I find myself over-revving the engine a lot. Causing engine damage. If it's been removed I guess I can adjust. I didn't even fully realize how much I relied on them until they were gone. Kinda weird I know. But I liked them being there.
My G27 Leds still working correctly. Must be a Problem by you. I would try to reinstall the driver/Logitech Profiler. You need the new one. Its updatet by Logitech this March. http://support.logitech.com/de_ch/product/g27-racing-wheel
