By understanding the position and the angle of the lights mentioned, the person at the helm (steering) of the opposite ship can clearly understand how much change needs to be done in the ship’s route. The visibility range of such lights varies between three miles to six miles. The lights that are used for ships and bigger boats have a longer range of visibility as compared to the...
