Work and testing is now complete for Seattle City Light’s upgrades on its iconic “CITY LIGHT” signs.

Seattle City Light contracted with Seattle-based Western Neon Custom Sign Builders to replace the neon lights in the iconic City Light signs at its South Service Center at 4th Ave. S. and S. Spokane Street with Optic Arts Flex Neon LED rope lighting from Lighting Group Northwest.

The new lights resemble the classic amber color of the original signs, which were built in the 1920s. The signs do not have Seattle landmark status, but they are the last remaining pair of full “CITY LIGHT” signs from that era. City Light historically had similar signs at its Yesler Substation and control center, the Cedar Falls powerhouse and the Lake Union steam plant.

Replacement of the neon lights in the South Service Center signs was needed because they outlived their expected life span and became hard to maintain. Using LED lighting will save energy and save money while maintaining the historical look of the signs.

A team of employees from City Light’s Facilities and Customer Energy Solutions divisions and its Lighting Design Lab designed the changes. The last upgrade to the signs was in the late 1980s.

The City Light signs are actually 18 separate signs. Each letter is its own, separate sign. One set faces west and one set faces east toward Interstate 5.

Seattle City Light is the 10th largest public electric utility in the United States. It has some of the lowest cost customer rates of any urban utility, providing reliable, renewable and environmentally responsible power to about 750,000 Seattle area residents. City Light has been greenhouse gas neutral since 2005, the first electric utility in the nation to achieve that distinction.
