Will traffic lights set off POP? I sometimes get a low weak signal on K band at some traffic lights but I was driving and getting real close to a light when my POP goes off once, i drive through the light it goes off again and a little past the light and it goes off again, I did not see no cops present and i turned off on a street asap and sped down taking a few turns lol! Also I was parked at a light and got a full K band alert, once again no cops in my view? Im using the X50 and im starting to ignore alerts and its only my 3rd day having the thing lol! Are these for real alerts on pop and full str k band or can they be fake? I have been to a few lights and got the same k band signal over and over usually weak. Sorry for all the questions, just trying to learn how to use the thing lol.
