Not all lighthouses are striped but all lighthouses need to be visible during the daytime, as well as at night. The stripes on some lighthouses increase their visibility.

Why are light houses often found on barrier islands?
Lighthouses are often found on barrier islands because these islands are located near coastlines and are susceptible to shifting sands and changing shorelines.

Additionally, the high elevation of lighthouses offers better visibility for sailors in the open sea.
