Where can i buy police strobes?

OK, first and foremost, i don't need a bunch of pu$$ies on this question, so i own a G35 coupe, and when i race, there is only so much weaving I can do between traffic till it gets slowed down to like 50-60mph kinda blocked up, so im installing,police edition...headlight stobes, grille stobes, and visor strobes, so when i flick them, people will move. i just want to know where i can get them at. and if someone else did this, hit me up wid an e-mail.
