Night Guard Light reversed after storm????

I have two gurad lights that normally come on after dark, and go off after sunrise. One is mine installed at the gable peak of my garage, and the other is installed and maintained by the power company on a telephone pole.

We had a bad thunderstorm a couple of nights ago (Dallas area), and now both guard light shine DURING THE DAYTIME and go off at night! What gives?

I'll call the power company, of course, to fix their guard light on the telephone pole, but, what do I do about mine that is on my garage gable?

I've never heard of nighttime guard lights reversing their function - I'm assuming the thunderstorm had something to do with it (the power got cut suddenly several times), but, if anyone has experience with this and can tell what's going on, please repsond.

Turn the power off to your light, then turn it back on.
If it does not work correctly, replace the sensor.

I turned it off and back on several times this afternoon and it always shone bright when turned on - broad daylight. So I cut the power and waited until after dusk and the street lights came on, and then I flipped the power breaker back on, and viola! the guard light came on. So, I guess it is back on track - for now.
Thanks for the suggestion.

They have electronic circuits in them, and the gates can get wonky if they get surges. Best thing to do, is install a whole house surge protector on your main power panel, along with making sure that you have proper earth ground for not only the main power, but also catv, satellite if you have, and telephone. EMI & RF can play havoc with today's pretty much electronic ran circuits.
