Does traffic light camera have to flash to work?
Most do at night but they also operate in the infrared spectrum so the light may not even be visible. The cameras also take running video before and after your crossing in infrared so they can see if you are in the intersection legally. You usually get a URL to see the video of your ticket and if you think you were in the intersection legally and that the video shows this, contest the ticket and see what the judge has to say. There’s plenty of lawyers that want test cases to work out the best defense against red light cameras with since there’s a lot of money to be made by the first law firm that finds a winning argument and these arguments may be different with different judges so you may be able to get representation for free.
