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
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...
