Arizona: Sahuarita’s ‘tattle-tale’ lights help cops do their job

Several red-light indicators installed two years ago to help Sahuarita police officers catch red-light runners are making a difference, officials say.
The indicators, known as ‘tattle-tale’ lights, are small blue lights mounted on the back of traffic signals that let officers know when a traffic light turns red, even when the officer can’t see the traffic light itself.
The lights, first installed in 2016, are in place along a stretch of Sahuarita Road that sees a high volume of traffic. The lights have been installed at five intersections: Rancho Sahuarita Boulevard, Salome Loop Road, Desert Gem Lane, La Villita Road and the Nogales Highway, according to Paul Burton, traffic-signal operations manager for the Town of Sahuarita.
