I've never experienced or heard of anyone who has had that happen. There is no way to swap the left/right around from the bike controls. As a starting point I'd check that the lights are wired correctly to the left and right. Typically Red (or Yellow) would go to the left and Orange (or White) would go to the right. Fastest way to diagnose would be to pop off the seat, turn the ignition on and unplug the red circuit to see which light turns off (assuming you are using Red for the left hand light).
