WOW! What a cataclysmic waste of money.
I look at guys with their POVs all decked out in a totally different way than I do other firefighters. Mostly it is completely unnecessary and is more a "Look at me, aren't I cool" factor than anything else.
I do have a serious question for you though. Why do you need an arrow stick?
I sincerely doubt that is only $300 worth of lights unless you bought them used.
Sorry, NO. Unless the FD is paying for any damages to my POV I am not using it to block or direct traffic. I wonder if your insurance company knows you run your POV as an emergency response vehicle. Some insurance companies won't even cover vehicles used like that that are privately owned. Good luck, because I see it as only a matter of time before your vehicle is going to get blasted and you will be screwed.
Posts like yours are generally frowned upon here because they tend to lend credence to the perception that vollies are whackers. Personally, I don't care one way or another, but be aware you may have to play quite a lot of defense on this one.
You are delusional if you believe running to a call with redlights doesn't make your vehicle an emergency vehicle in the eyes of the law. Further if you are acting as a firefighter, and believe me being a volunteer doesn't exempt you, and you block the road using your redlights your vehicle IS an emergeny vehicle.
And further don't play the "I am a volunteer look at me card" because I am a member of 2 paid on call FDs (volunteer), as well as being a career firefighter and it doesn't fly with me.
