Both wireless wheel AD and wheel lights have passed compatible testing on windows 8. When we first install LeLight!HD and Lelight!RA on windows 8, the system pops out a warning message. It is because window has not yet recognize our software. Please go ahead and click OK button to finish the installation procedure. We also upload several patterns via USB transmitter to our lights. The transmision time and the final result were as good as we expected. Now, our software can work on Win XP | Win Vista | Win 7 | Win 8. Mac version is under developing and is schduling to release in 2013. If you have any question or feedback, please feel free to let us know.
