WTB: Federal Signal Lightbar

[Motorsport1]

Looking for a correct 48" Federal Signal Jetsonic lightbar for 89 FHP, Thanks!

How is a correct FHP lightbar set up? I have a few sitting around, maybe one will be correct.

Not really sure, I found this right up under a restoration guide for the FHP cars...


For the first year, a Federal Signal CJ184 Beacon with blue lenses was deployed (see image #1, above). After that, and for the duration of the SSP program with FHP, a Federal Signal Jetsonic 48” lightbar was used on all Mustangs, with some exceptions, notably the Vector equipped cars. Based on the JS1 which was introduced in 1983 by Federal Signal, this lightbar was actually a JS2, due to a 100w speaker and PC control board not available on the JS1; Oddly enough however, FHP documentation refers to it as a JS1.

The JS series lightbars were initially equipped with a single Bosch motor which turned the chain controlling the rotators. These lightbars were unique in that they were chain driven/gear rotator design with 4 flashers. The "brain" utilizes the rotators as flashers; they rotate to a predetermined spot, and then stop rotating and flash. Because of the slow rotational speed, there was an old trick among Troopers to substitute a rubber band for the chain to ensure the rotators would turn much faster! These lightbars were ‘high current’ draw devices, not only because of the motor assembly, but also the 50w Halogen bulbs that were used. High output alternators were ordered on all FHP cars after they became available to help support the demand for enough juice to run these (and all the other required items) being fitted in the cars.

The JS lightbar used only blue and clear filters, and again, was the rotator variety, not strobes unlike other agencies deploying these lights. Clear filters on the ends, two clear takedowns on the front, and the rest are blue on the Jetsonic equipped cars. The siren was a 100w unit mounted in the middle; unmarked units also used a 100w siren mounted facing down or inwards, just below the headlamp housing, on the drivers side.

FHP had a ‘signature’ of using the two outboard fronts as takedowns, along with the alley lights. This, coupled with the Unity S6 6” spotlight on the marked units, provided additional lighting for nighttime traffic stops.

Guys, there is a resource right here on the site that answers those questions (without BS about rubber bands on the lightbars)....

There is also a picture of what the correct bar looks like in that document:
