Underhood Sirens
I am interested in getting a small, underhood siren for my 68 MM combo, but I am unfamiliar with sirens and what would have been put on my car back in 1968, and also what will fit in it.

I was looking at Federal 28s but i am not sure whether or not that would be period correct for my car. Can anyone provide any insight or resources for me in regards to sirens?

I have a functional Federal Interceptor in my 1976 which, as far as I know, is original to the ambulance.

One of the better articles I found was:

If you intend to make the siren functional, make sure the under hood speaker is rated for the wattage of your siren.

It should go without saying, be careful to observe the rules in any car show or parade.

The 28 under the hood would be correct. The are a loud siren. normally mounted side ways behind the grill. If you are lucky the plate for it will still be there. We get out of PT I can post a few pictures of the setup. It's the same on my 67. They did have a 65-68 set up that went into one of the bumper pods. But it was only a 5 inch siren. I had one on my 68. It went with the car.

I believe I do still have a plate last I checked, not sure of how much room though. I will get a picture

here you are the superior mount and the 28 mounted on it. plenty of room. and this is the federal 58cs that was designed to go int the front bumper pod

I added a 28 to my Lifeliner and mounted behind grill. It's my third siren on the rig.

WOW, no wonder you canít be in the parade, lol:D

Thanks for the info. I know behind the grill there are several things in the way, so i will see if there is room around the plate. There is a small speaker that says "play horn", I assume thats the horn, kinda weird name for a car horn though.

I will keep my eye open for one when I have a little bit of extra cash.

At a car show this past weekend someone was talking to me about sirens and suggested I look into cattle sirens as they sound the same. I looked into it and while they do sound similar, the wind up speed seems a little fast and the price difference for a pierce cattle siren and a old federal are mostly negligible.

If any of you have an extra siren, i may be willing to buy. It doesnt necessarily need to be a Federal 28, but anything that sounds authentic and could be mounted behind my grill or opposite to my battery.

I actually had found some yugoslavian siren on ebay and am currently keeping an eye on that as well.

depending on how loud you want the siren to be, you can buy a burglar alarm siren very cheaply. I might even have one in the garage that you can have for the shipping cost. If it interests you, send me a PM, and I will take a look... Paul
