My goodness, look at the 'growlers' they've stuck on the front of this truck! TheFireman, it appears that chrome 'thing' between the two red strobes? is a wig-wag lamp? or another siren?
Pavel, It is what we call a Mars Light. It "wobbles", if you will, in an up and down pattern with a very bright white light to get attention in rear-view mirrors. That is the theory, the problem is not many American drivers check their rear-view mirrors often enough. As far as the "growlers" ( I like that!), the Federal Q2b mechanical siren is rapidly diappearing from American Apparatus. In our department, they have gone to all electronic sirens. Federal has built an electronic version of the Q2b, but it's not very loud and the sound is poor, like a sick cat squeeling.
Ok Professor, YOU SERVED on this rig, but you don't recall where? Kinda like saying "Thats a picture of my mom!...I don't recall her name"

Don't recall where? I clearly said that I served on that engine (TCFD Engine 41) and clarified that it was RECYCLED FDNY. Kinda like saying "My name's Sammy and I can't read too good."
Mars Lights, from Mars Signal Light Co., were used on a number of North American Railways - on both steam and diesel locomotives, and rail-cars [self-propelled passenger coaches]. They came in both red and white colours, and a variety of 'gyrating' motions - "figure-of-eight" was one.
They were were developed in 1930's, by a fireman, Jerry Kennelly; a Chicago FD, Illinois, Aerial Ladder Truck Driver; trying to get his rig through the traffic. Frank Mars, of the Mars Candy Co. [ ? today's Mars Bar ? ], collaborated with him. 1936 got the railways interested in some trials, and then the idea got adopted in service.
