Silly amounts of times me and mates have been out riding at night and pulled by PCSOs for not having lights, they warn us and let us go... only once has a mate got fined, but he was questioning the PCSOs rights so i think they just thought mehhhh hes getting it! I think its just how you treat them that decides what you gonna get, be polite, listen to them they shouldnt really need to give you a fine or even a warning... aha i just think your unlucky if you did get a fine!
