Re: red lights
That's a very confusing context for this.
The red lights indicate that camera is recording/broadcasting.
But a red light is also something that keeps you from proceeding on your journey.
I don't know what this person meant. Maybe he was so overwhelmed by the whole experience that all he could do at that point was look at the camera and just try to keep talking?
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
