Yes, you can see 2 windows, but that thing straight below the cockpit is probably a runway turnoff light.
It doesn't look very powerfull, so it's probably not that, but it's a guess, I'm not familiar at all with the C-5. I'm more familiar with the civilian Lockheed planes (On the 1011, the runway turnoff is at the wing root, directly above the landing light).
