Blue lights on top of stop lights

I was in Orlando yesterday and noticed small LED like lights setting on top of the traffic lights. It came on when the light was red, went off on green. What is it's purpose?

May also be Notice to the "Peace Officers' Traffic Light Changer Actuator" - tells the approaching Officer that the Light will change right away.

You can see the blue from the crossing directions when the light is red. Lets LEO see if someone is running a red light. At least, thats the way they are set up here in Gainesville.

Yeah, I'll bet that is what it is....

Some traffic signals are fitted with sensors to pick up strobes. When an emergency vehicle approaches with strobes active, the sensor causes the signal to change to green.

Llama is correct.

Nunn is correct.

These lights when used in central florida are to allow
leo's to see if you run a red light when they are out of position
to see the red or green light directly.
In other words, mostly when they are staking out the intersection.
Most of the time these intersections are ones that have had multiple accidents
due to red light runners.

the strobes over traffic lights here only flash when there is actually an emergency vehicle accessing the intersection. why they are blinking all the time is beyond me.
