Calipatria is a small town in Imperial County, California about 35 miles from the Mexican border. This picure is looking West on Main St, at the intersection with Hwy 111 which runs up the east side of the Salton Sea.
Can you see what is of interest, lighting- wise, yet?

At first sight this looks like a series installation of suspended NEMA heads, doesn't it? Of course the closeup of the light in the lefthand top pic shows that this particular one wouldn't work...
These fixtures clearly were series at one point, look at the insulators on the head, and the insulators on each side of the span wire.
Have a close look at the fullsize verion of this pic. It shows the pole at the side of the street that one of the spanwires is attached to. The spanwires for two separate lights are at the very top of the pole. If you follow the wire from the one on the left, you can see it enters a short length of conduit, and reemerges further down where it is connected via an ordinary photocell to the supply. So despite the hot and cold supplies to each fixture coming from different poles, it is still a line voltage system rather than a HV series system. The conversion from series to multiple was done not by rewiring the fixtures as is normally done, but reusing the old series wiring and retrofitting the fixtures with line voltage ballasts.
Oh, in case you were wondering, all the lamps are HPS!
