There is a strip of lighting on the north side, too, which illuminates that empty area of cladding above the uppermost windows.
It first lit last Thursday (that I saw), and has been lit each night since. I haven't seen it flash, but you can tell there's a differential output between segments of illumination: they are either not voltage matched or (like what happened to the decorative lights early on) misaligned. Further, the color temperature (warm) is stunningly different than the south side's SuperStrip (cold).
