uhh this kinda happened to me tonight, but I just assumed it was weird timing.
As I recall, I passed the lamp on the highway and saw it flicker off.. thought it was odd, but then another lamp right after that did it too..
Anomaly, probably.. but it could be a combination of timing/city cutting power costs/ghost lights..
Or maybe its all BS..?

Seriously though tomorrow night I'll try to get a video of it made. It does it 9/10 times I drive through this one road, another road does it around 50% of the time, and the highway random lights shutoff

when the photoeye sences light it turns the light off.... i suppose if his lights are horribly aimed they could fake the sensors into thinking it is light out and turning them off.
I know my bright flashlight will turn off those solar power lights for sidewalks...

Unless you have headlights that track an object thats 15 feet above you as you approach it and pass it.
The sensors have a time delay so lightning and such dont fool them.
I know of no street light with sensors that react in any less time
than 20 seconds of continous bright light.
Approaching headlights are just not bright enough and as soon
as you get close enough for them to be bright enough, the street
light is no longer in front of you but overhead out of the beam of
the headlights.
Solor Powered lights for sidewalks are instantanious in their operation...
Street lights, NO.
MH and HPS bulbs on the verge of burning out 'cycle' at the rate of
5 min on and 10 min off until they are dead.
They have bi-metallic strips in them that react
to the heat and switch a resistor in and out of circuit dependent
of the heat being produced. MH and HPS bulbs are tricky suckers...

The street lights are overhead when passing them, and the headlights are pointed to the horizion.

Older street lights will re-act after getting too hot and turn off, they usually do it in order because they come on in order. Newer street lights run more efficient so they don't do this.
Also, street lights still go on timers and will turn off and back on in order. I have seen this myself just sitting someplace and noticing it.
If you want a conspiracy theory (please dont believe it) look up SLI (Street Light Interference) some people believe they emit signals which turn off lights

Produce the proper strobe rate and all the lights will turn from red to green for you.
Fire Trucks have this and some foolish people have tried it with great success...
Kits are available on the internet.
