Interesting. It isn't glowing, though. For all we know the original TOS deflector assembly could have glowed with energy had the ship chosen to use such components but we never saw it. The NX-01 and other NX-class starships of the 22nd century had both a physical deflector dish and a blue glowing assembly directly behind it so if that did glow at some point at least it would fit in with established Starfleet history.
