Clearwater, Florida -- On Tuesday red light runners caught on camera in Clearwater starting getting $158 tickets in the mail.
Oldsmar will also turn on four cameras on Wednesday.
More than 70 Florida communities now have them, while cities in other states are getting rid of the red light cameras.
Clearwater City Councilman Bill Jonson says they're trying to improve safety.
"Our goal is not to issue tickets. Our goal is to change the behavior of motorists," Jonson said.
But cities in California, Georgia, Maryland, Tennessee, and Texas among others have decided to turn their cameras off.
In some cases it's due to legal challenges, while in others it was decided they just weren't effective.
"This was a failure. We were able to give people $500 tickets, but not necessarily improve any of the safety in the those intersections," said Los Angeles city council member Eric Garcetti.
St. Pete Beach approved the cameras last year, then a few months later decided not to install them.
In the case of Clearwater, city council gave itself a way out of the program.
If the cameras don't cut red light violations by 15 percent in the first six months, council can pull the plug.
"So after six months, we're going to see how it works out," Jonson said.
Another factor for Clearwater could be the makeup of the city council.
When the cameras were approved the vote was 3-2.
But two of the council members who voted for them, are no longer serving.
