I had once an issue of not being able to turn the lights off from the cyclo computer. Well, actually they did finally go out as soon as I turned the bike battery off. So, if this is somehow related to the computer, maybe you can try resetting it. In general, the computer is losing connection to the bike from time to time.
Did you ever get your light situation sorted out? I noticed in another post you're in NY. We're in the process of getting setup as a Turbo dealer at the moment so I just wanted to let you know if we could help in some way.
