my boyfriends b-day is coming up i want to get him something for his car i was thinking undergourd neon lights anything that lights up blue if t here is any websites out there that i can look at i would appreciate any advice or ideas what is something a guy would like for his car . i know hes been wanting to get something for his car anything from car audio to lights he already has head and tail lights already(new) but anyway i need help asap!!!!!!!!!!!!!this is for arizona gr... first of all underground neon lights are not illegal when the car is parked for an example if the car was at a car show or meeting ( which is where the car is always at) but it is illegal to drive with them on . because it causes so many distractions so...therefore it is fine to have them and about them being ugly that is YOUR opinon they look good on just about any other car. i know all this because my father is a police officer and i am studing to design cars as graphics not many girls love cars as much as i do so please i asked for a question not a smart remark and i thank you very much for your ideas about what to get him ill keep that in mind.....he already has an air intake and a exhaust. thank you very much!
