At night, the color-coded patterns of marine navigation lights help mariners determine the size, type, and direction of marine craft. This exhibit helps visitors decode these light patterns by using a half-silvered mirror to superimpose images of common ships and boats on the water to clarify their identifying characteristics.
This exhibit is part of the collection: Fort Mason
