Blue lights above traffic signals on state roads verify traffic violations

Blue lights above traffic signals  are called "tattletale lights" or "red light confirmation lights."   Whenever the traffic signal is red, the blue light is on.

Police previously had to testify that a vehicle was in an intersection when it ran a red light.

Now, officers only have to see the blue light to know the vehicle ran the red signal.

Florida Department of Transportation officials are paying for the lights at intersections on state roads in nine Central Florida counties, reported a representative from the Florida Department of Transportation.

Originally, the DOT put up small white lights at a cost of about $100 each. The DOT is switching to less-expensive blue lights, which are LED (light emitting diodes) that run cooler and need less maintenance.

Running a red light in Florida can bring a fine of $188.50.

Violators also face adding three or four points to their driving record, unless they complete a state-approved driver-safety course.
