do not believe anything you read about radar jammers working. I have bought and tested every radar jammer there is with a police car, even the $2,500.00 ones did not work.(but they did set off everyones radar detectors which was fun). I have been to the guy that owns most of the radar jammer companys house it is just an hour from me, and when i was there he told me that if he put a rock in a plastic box and sold it for 200 and told you it jammed radar that he would only get 5% of them back. that should tell you something.
now for the real life stuff. if you are getting hit by lazer you can get a bunch of halogen off road lights and put black abs plastic over them to where the visible light is not seen, it will reduce the length they can radar you from. I have tested this with 4 160 wattt lights on a little car it reduced the radar range to about 150'.
