Updating the lighting on our donated engine. its a 82 Pierce. Has the old silver square box opticom strobe on the roof. Inside the cab has 2 switches for it, theres 3 style patterns. Question is this. Im putting a new lightbar on and since we dont use the opticom (we dont have the system in our city) its probally going to come off. What are these worth? I know someone out there with a 70s-80s truck would want this.
 
Depends, is this the totally "self contained in the silver box" less the switches type, or the "thirty parts and cables" type? :p


Whats the overall condition of the strobe tube, and uh.. condition?


Also, brand, model, etc... Photos would help too.


Oh, and 3 style patterns? Can you list them off? I only know of two "pre-emption" patterns.
 
yup thats the one. it has 2 of those control boxes, stracked on top of each other.


was going to pull it off but the higher ups decided its staying on engine.

Snap a couple of shots of the engine and the unit installed. Must be a piece of history.
 
I saw the demonstration when these were acquired by the City of Knoxville around 1975.


There can be multiple levels of preemption:


Turn light green in direction of travel,


Lock-up all intersection lights red;


hold a stale green longer (keeps light from changing, useful for passenger buses and aerial apparatus)


determine priorities for type (weight and size) of apparatus


Also, most of these lights were filled with a fluid to dissipate heat. I don't think it was just water, and fluid that would be necessary to protect the light and strobe.

It was the first emitter made by 3M, Opticom model 172 ( below ). If anyone has this unit, please contact me.

These were later replaced by Model 192, which is basically the circuit board, strobe, shiny reflector and aluminum casing; no fluid.
 

Any idea what year the Model 192 came out? I am looking for an era-correct opticom for my 76' squad car.
 
Anybody have an idea on how bright these are supposed to be? My department just got an 85 Pierce Arrow with a 3M opticom like above, but it isnt bright at all. Just wondering if this is right or if something is wrong with it.


Thanks,

Strobe tube is probably past its life cycle. Take a look at the actual bulb for black/white hazing near the ends/ along the tube, and or other defects.


They normally are bright as Snot.
 
Sorry to drag up an old post but I have a question. I found someone with a strobe bulb for my departments opticom, but it doesn't have the liquid in it. Can I use one that does not have liquid in an opticom that originally had liquid in the bulb?

I've been using a portable - hand held Opticom, and it's not very bright at all, like typical strobe lights, but it sure gets the job done.
