SurvivingChecked on "as of" date (either in person or via latest GSV available), so can be assumed to be surviving at least as far as that date
as of Jul 2019 but replacement slated to start this year
This is a well known installation, but that doesn't mean it's not important- as far as I know, it's still one of the biggest incandescent radial wave systems in the US, which considering it has survived maybe 80 years intact, is no mean feat. The pics were taken in 2004 and 2013, and they still hang on. However, the fact that in 2013 all cities are running low on their stock of lamps means that this sight's days are numbered.

This is the Arroyo Seco area, we're on S Arroyo Blvd, and these lights run from the intersection with Madeline and Grand to the south, up to (almost) where it runs under the Colorado Blvd bridge, which itself used to be lit with incandescent fixtures until they were recently changed to CFL. At the southern end they are also on a few roads leading from Arroyo Blvd to Orange Grove Ave. Bellefontaine, Madeline and Bradford are some good streets to check.
