I wouldnt worry mitch, to be fair, I know very few drivers who drive through a flash box that will NOT apply their brakes, its the paranoid nature those things have imposed on us...
As Dan Said, they use the two photographs taken and calculate the distance the car travelled... Speed = Distance travelled / Time, as they know the time difference between the two snaps, and the distance is translated from the lines, then they work out that he was flying by and you werent.
At the end of the day, they would need to prove you were speeding, and applying your brake lights is no evidence. Plus these things, (depnding on the type)... If its Gatso, it will be first activated by the radar signal being reflected by the vehicle its pointing at (the oncoming driver) that triggers the flash, if its a "Truvelo" then it is activated by the driver approaching the embedded sensors. That could be either of you.
I wouldnt worry, unless you were speeding, the pictures will show that your car was travelling at a safe speed, if they see that the other vehicle was travelling faster than you then the ownus of responsibility is on him...
I do like learning about this random cack
