Flashing → It is formed from "flash" (of uncertain origin, possibly imitative of the sudden burst of light) and the suffix "-ing" (indicating the action or process). The word "flashing" refers to the action of emitting a sudden burst of light or brightness.
Think of a sudden burst of light when you hear 'flash' — the '-ing' shows it's happening right now, so 'flashing' means something is currently emitting light.
