Default Little blue light under traffic signals???

Just curious as to what the small blue light is for at the bottom of certain traffic signals. Seems they are all on when the corresponding light is red. No one I've talked to seems to know. Some ideals floated past me are for color blind (can I say that? Is it now color impaired?) drivers or for law enforcement so that they can tell if a car is running a red light no matter where they are sitting. Anyone know for sure?

They are for Fire/EMS to control the light from the cab or their trucks

We have something similar here in Chicago and I've been told they are there to inform deaf drivers that a fire truck, ambulance, or police car is coming.

MikMal, You were right when you said they are for law enforcement to use when enforcing the laws against ignoring traffic signals.

By use of the blue light system an officer can testify about a violation that he saw from an angle that would not have afforded him a view of the actual red lense the violator had ignored.

+1 Exactly! The blue light goes off when signal turns green. When the signal is red then the blue light is on.

That was what I thought to be the most likely explanation. While working in the emergency services up north, we had intersection control devices like some posters suggested but they were simply a sensor; no light too. Plus, I've seen ambulances go through intersections here where the light did not change to their favor. Thanks for the confirmation. Learn something new everyday!

No clue what your little blue lights are under your traffic signals but here in our city, they have installed cameras that feed back to our local police station..they are everywhere. We had a siege of shootings and stabbings a year or so ago and the police have now become actively involved in a high tech way. Since the notice went out in our local paper about these cameras and where they were located, things seem to have quieted down. One can only hope!

Down here, a lot of cities have installed "red light cameras", which is absolutely nothing more than a way to gain more revenue. Head through the intersection just as the light turns red, gotcha. Your ticket arrives in the mail a week later. They were gaining popularity across the nation, until recently. Several FL cities have now removed them due to constant public outcry and legal pressure.

Red light cameras tend to create problems of their own.

First and foremost is a defendant is supposed to be able to confront his/her accusor and in many areas the red light camera tapes are monitored by clerks employed by the company who won the bid to install and operate the cameras. So in effect, you are getting a ticket from some clerk in a computer lab, a week or more after you drove through the light. You may not even remember the event. You may not even have been the driver but the car is registered to you.

In Lee or Collier County the biggest complaint from the public was for getting tickets for Right On Red violations of making a "rolling" stop. Obviously they made it through the light safely and a cop would not have bothered to stop them, much less issue a ticket. But those clerks in that computer lab would issue the ticket because their company may get a fee for each summons issued. I say may on that because I am not sure. But still it is not police officers making the decision to issue a ticket. Even if it should be a police officer, not being at the actual event leaves some factors out. But at least an officer would be more reasonable.

The police have the ability to use discretion on each and every traffic stop. They may issue a summons or give a warning. They evaluate the violation, circumstances and demeanor of the specific driver stopped. You loose this professional training and behavior when you subcontract traffic enforcement to those who simply are trying to get the most out of the camera system.
