In 1909 and 10, the Siren was coming in to use on automobiles as a horn. Known as the "Mile Ahead" electric horn the SirenO was used on many cars of the day. I found an article where it became such a nuisance, that some areas passed laws to ban them.

I like how Federal takes a jab at PA, CA, and VA for not using clear/red signaling on their emergency vehicles.
"You don't know how well this works! It's so obvious to everybody else but you guys! What's your beef with clear/red, mate? Get with it!"

The last invention of the 60's that I have is a design by Robert J. Forestal, and the Dura Corporation of Southfield, Michigan. His design of a "platform for carrying emergency signals having a lazy-tong structure". The platform is controlled by an electric motor and is mounted on the roof of an emergency vehicle. Actually quite an ingenious idea, if not a truly practical one. He notes that when emergency vehicles are on scene, the lights are often obstructed by other vehicles, and are hard to see from a level plane from other cars. Also the spotlights and alley lights are of little use for scene lighting at roof height. This platform would allow the lights to be elevated to increase their visibility and to light the scene better. This platform system was used in Air and Light trucks in many fire services vehicles.

Skulldigger, thanks for posting these great flyers!! I remember a 174 flyer explaining how the oscillating pattern allowed the eye to perceive the dwell at TDC as much brighter.
