the lighting system. Avoid heavy pressure and use of caustic or petroleum based
products when cleaning the lighting system. Replace any optical components that
may have been scratched or crazed during system installation.
• Do not attempt to activate or deactivate the light system control while driving in a
hazardous situation.
• Frequently inspect the light system to ensure that it is operating properly and that it is
securely attached to the vehicle.
• After installation and testing are complete, provide a copy of these instructions to

Introduction
The Rear SpectraLux ILS is a single-level LED light bar that mounts in the rear window
of the vehicle. It uses ROC (Reliable On Board Circuitry ™ ) technology, and Solaris ® S2
reflectors. The light bar operates at a nominal input of 13.6 Vdc (11 Vdc minimum). The
functions of the ILS are controlled through the CAT5 serial communication cable. The
cable connects to either a compatible Federal Signal Serial control head or a Federal
Signal Serial Interface Module (document P/N 8583446). An internal PCB assembly
within the light bar decodes the control data and performs the requested function. With
the Serial Interface Module, the light bar can be activated by Federal Signal light bar
controllers, SignalMaster ® controllers, and/or individual low-current switches.
The backbone is a powder coated aluminum shroud. The light bar has 15-foot power and
ground cables and a 25-foot serial cable. Mounting hardware is a configured option. Refer
to mounting instructions supplied with mounting hardware. The light bar has an operating
temperature range of –30°C to +65°C (-22°F to +145°C).
Unpacking the ILS
After unpacking the ILS light assembly, inspect it for damage that may have occurred in
transit. If it has been damaged, do not install it. File a claim immediately with the carrier,
stating the extent of damage. Carefully check all envelopes, shipping labels, and tags
before removing or destroying them. Ensure that the parts listed in kit contents list are
included in the package. If you are missing any parts, contact Customer Support
at 1-800-264-3578, 7 a.m. to 5 p.m., Monday through Friday (CT).
