Two sets of lights is going to make the ANT+ light controls more trouble than it's worth, I think - you'd have to go in to your head unit to turn one off and turn the other on, and that's in addition to physically swapping them out. At that point, I'd just control them manually. Unless they're much smarter than I assume... I mean, it'd be cool to have light priority that automatically lights up the next in line when one dies, but I would be pleasantly surprised if the protocols were that fleshed-out.
