Been a while since I've flown the Astar but I seem to remember the bleed valve light was green. Used to fly with the pitot heat off sometimes and that was a yellow light. The fuel gauge seems to show enough fuel in the tank to keep that light out. Perhaps it was the " person taking a flash picture in the cockpit at night while the pilot is on approach" light. No, that should be a red light i think......
.
Anyway, glad you had a good time. The Cradle of Aviation museum is good, but a little further down the Long Island Expressway is the American Airpower musuem with a bunch of flyable WW2 fighters/bombers and the themed restaurant called the 56th Fighter Group. They are both located at Republic Airport.
Cheers
