What should a row boat be able to display at night to prevent a collison?

A rowboat should display a white light visible from all directions at night to prevent collisions. This light can be a lantern or a flashlight mounted at a high point to enhance visibility. Additionally, it's advisable to use reflective tape or materials on the boat's sides to increase its visibility in the dark. Having these safety measures helps ensure that other vessels can see the rowboat from a distance.
