Any Seattle Fags have a pic of a covered vault light?
moar vault lights
the 1840s as deck lights for ships, vault lights were popular in cities, including New York, Chicago, Victoria, B.C., and Boston, from the late 1800s through the 1930s, when electric light prevailed. All of the prisms were originally clear and have since turned purple due to magnesium dioxide, which changes color under long term exposure to ultraviolet light. The reason you don’t see more in Seattle is that individual building owners are responsible for the vault lights in front of their building and it’s cheaper to cover them over than to upkeep them.There are still about 9,000 vault lights in the city.
