The signal shown here is a pretty typical California traffic signal assembly, using curved/upsweep mastarms and two signals on the arm and one on the pole itself. The left signal head usually has arrow lights for protected left turns. Traffic signal and streetlight combinations are also very common in California, as you can see the streetlight above the signal. This signalized intersection is also home to two mercury vapor AE 25s, 250 watts. You can check out the neat photos below of the lights warming up to full brightness as the sky turns to dusk. Enjoy!
