That looks extremely expensive, but too awesome not to spend the money on those lights.
I actually hope they illuminate the entire ride, similar to Gatekeeper. The ride is beautiful, so they might as well show it off as much as they can. Plus, riders will get to whiz past all the lights. One night ride on Top Thrill Dragster and you'll realize that the blur of lights streaking by you makes the ride nearly as fun as a pitch black ride.
