:iagree: It really depends on your state. I have a siren, but can use ONLY the air horn function of that siren, and that's all I use. I have no need or desire to lose my license for impersonating a LEO.Yeah what Coyote said. I'm pretty sure that you can't use a siren in any state but you should really check your state's laws.
As far as the strobes. If you are parked on the side of the road, and they warn people of a hazard, I would see nothing wrong with that. I have used mine (blue and white) when pulled over on the side of the road when other's have broken down. You can't be too careful these days. You're not putting them on to get through traffic or pretend to pull people over, so I don't think a LEO would have an issue unless they are having a REALLY bad day.
I would not use the air horn until you find out about your local laws. I believe you when you say you don't use the siren, because I do the same :yes:
