Hispanic aldermen pushing for a boycott of all things Arizona to protest that state’s controversial immigration law might hit a red light.

Chicago’s 189 red-light cameras were installed by Arizona-based Redflex Traffic Systems, which put in the cameras and road sensors. It also operates the software and mails out the $100 tickets along with photographic evidence of the alleged red-light running.

In 2008, the Daley administration signed a five-year, $52 million contract with Redflex that cut the cost of each camera system from $100,000 to $24,500. It also included maintenance for cameras installed after Oct. 22, 2008.
