One man could take the credit for changing a state law in 2013.
Eric Campbell sued after Florida Highway Patrol troopers issued him a ticket for flashing his headlights to warn other drivers about a speed trap.
"As I came over the overpass, I saw two troopers with their lights off at night. You couldn't tell they were there," said Campbell.
Troopers pulled him over and told him because he blinked his lights five times or more, it was illegal. He got a $101 ticket.
But Campbell wasn't ready to give up. He said it was his right to flash his headlights if he wanted to.
"I ended up finding another case that was very similar to it, contacting the attorney that defended that person, and it went from there," said Campbell.
His attorney estimated more than 2,000 drivers were issued the same ticket in a four-year period. Once Campbell and his lawyer filed the lawsuit, FHP sent a memo to all troopers telling them to stop handing them out altogether.
A few days ago, with the start of 2013, the law officially changed.
Campbell has already gotten letters in the mail from strangers.
"They just say 'Atta boy,' " Campbell said. "Some from really old people, the handwriting is scribbly. They say they've had similar experiences and never had a way to right the wrongs. So they really appreciate somebody that stood up for them."
Campbell said it would have been easy to pay the ticket and move on. But he wanted to stand up for his civil liberties.
