A vehicle display system displays approach lights acquired by a vision system overlaid on, and aligned with, a stored synthetic approach light symbol. A stored approach light type that corresponds to the target runway may be verified to match the acquired approach lights. A synthetic approach light symbol that corresponds to the approach light type is chosen and aligned with the approach lights for display.
