What lights must streamer down show at night?

During nighttime, a streamer down (a vessel under 20 meters in length engaged in recreational activities) must display a white light visible from all angles. This light can be an all-round white light or a combination of a white stern light and a white masthead light. Additionally, if the vessel is anchored, it should display an anchor light, which is also a white light visible from all around. It's essential for safety and visibility on the water.
