At 109 years old and still burning (and in the Guinness Book of World Records), a real light bulb hanging in a California firehouse not only merits admiration for its durability but also provides a natural anchor for a look at how a small settlement grows over a century into a city. Nolan takes it decade by decade as, in Lafrance’s folk art–style acrylics, ever-larger buildings go up around one fire house after another, a hand-pulled hose cart gives way to a succession of fire trucks and the professional firefighters who succeed volunteer companies put out fires, perform rescues and march in parades. Beneath the bulb they welcome generations of marveling visitors in changing period dress. Unlike Juliette Goodrich’s Little Light Shines Bright, illustrated by Roseanne Lester (2008), there’s but one actual photo, but the little-town-over-time theme—and the fire trucks—exert plenty of child-friendly appeal. The bulb has its own website and webcam. (afterword) (Informational picture book. 6-8)
