Flashing is layered protection. So what is flashing? It's a thin layer of waterproof material that keeps water from getting into places it doesn't belong. (Caulk is fine for filling small gaps around windows and doors, but it shouldn't be confused with flashing.)
What Are Flashing Lights? When flashing lights occur you may think that you see lights going on and off, especially to one side. These tend to happen in only one eye at a time, even when your eye is closed. What Causes Flashing Lights? The vitreous sometimes pulls on the retina. This may cause you to see flashing lights or lightning streaks, even though there aren't any such lights present. This is the same thing that occurs when you get hit in the eye and see stars or when you rub your eye.
