A new device, much like a radar detector, can alert drivers to locations where red-light cameras have been mounted. The company that?s come up with this is Cobra, long known for its dashboard-mounted radar detectors that alert drivers to police speed- radar monitoring devices.

Because red-light cameras don?t emit a signal, this equipment uses Global Positioning Satellite technology and a database to tell you when you are near an intersection with a red-light camera.
