I will happily expand... but remember this is my opinion based on experience and I am not bashing any groups, so please don't take this as that.
I think the OP Jeremy has his heart in the right place, but I think that this is going a bit far. I can tell he is young, and we have all been there (or are there). Far be it from me to say anything about someone having a bunch of radios in the car, as I do myself. My Honda Crosstour install thread is in this forum a page or so back.
I think that what Jeremy needs to remember, both as a young person and as a potential first responder in a small town, is that his reputation that he forms now will precede him for a long time, if not the rest of his life. Having radios is one thing, it's a hobby that we all enjoy. When you start adding emergency lighting just because you want it (note that there is a difference between WANT and NEED) and justifying its use, that comes close to crossing the line. If you have to ask yourself if you are a whacker, the answer is probably yes.
There is no situation that I can think of where I would assign ARES to direct traffic, nor would I ever think about authorizing them to have emergency lights to respond to a station to talk on the radio. There is a good reason that ARES is often seen as getting in the way.... I have nothing against them, but it's the truth. With the technology that we have today such as mobile radio and cell towers on trailers, commercial satcom, commercial HF, wireless internet, etc the notion that ham radio is still the "last line of defense" is kind of a joke anyway.
If Jeremy makes a name for himself as a whacker, he can kiss his chances of a PS job goodbye. Further, all it takes is one person to mistake his good intentions for impersonation before he has his local agency's intelligence squad at his house to interview him, which will result in a "Possible Impersonator" bulletin going out across the state and sealing the deal. Many a ham or scanner enthusiast has been quickly labeled a nuisance after going on self-appointed safety patrols. We hear about these guys often, and some are or have been on this forum.
If he wants to contribute, I think that showing restraint and professionalism while at the same time expanding his knowledge of emergency services, communications, and emergency procedures would really benefit and open many doors for him. I think that his current path will slam doors shut. Again, most of us have been where he is now, including me.
My 2 cents.
