INSTALLATION AND MAINTENANCE INSTRUCTIONS FOR
HEAVY-DUTY RAYDIAN® LED LIGHTBAR
SAFETY MESSAGE TO INSTALLERS AND USERS
People’s lives depend on your safe installa-
tion of our products. It is important to read,
under- stand, and follow all instructions
shipped with the products. In addition, listed
below are some other important safety in-
structions and precautions you should follow:
• To properly install lightbar, you must
have a good understanding of automo-
tive systems, along with proficiency in
the installation and use of safety warning
equipment.
• DO NOT install equipment or route wir-
ing in the deployment path of an air bag.
• This product contains high intensity LED
devices. To prevent permanent eye dam-
age, DO NOT stare into the light beam at
close range.
• A light system is a high current device. In
order for it to function properly, a sepa-
rate ground connection must be made. If
practical, it should be connected to the
negative battery terminal. At a minimum,
it may be attached to a solid metal body
or chassis part that will provide an effec-
tive ground path as long as the light sys-
tem is used.
• When drilling into a vehicle structure, be
sure both side of the surface are clear of
anything that could be damaged.
• Locate the light system controls so the
VEHICLE and CONTROLS can be oper-
ated safely under all driving conditions.
• The mounting system should be periodi-
cally inspected to ensure that it is secure-
ly attached to the vehicle.
• File these instructions in a safe place and
refer to them when maintaining and/or
reinstalling the product.
Failure to follow all safety precautions and
instructions may result in property damage, serious
injury, or death to you or others.
I. GENERAL.
HEAVY OBJECT
Get assistance when lifting or installing.
Failure to do so will cause permanent bodily
injury.
The Raydian is a LED light bar, with supplemental
white halogen area lighting, designed for use with Federal
Signal lightbar controllers and/or single switches rated
at 2-amperes and above. The base is a two piece extruded
aluminum profile with polycarbonate lenses and end
domes. The unit is supplied with mounting hardware and
a thirty-foot cable, and has an operating temperature of
–40oC to +65oC.
II. UNPACKING.
After unpacking the Raydian light assembly, inspect it
for damage that may have occurred in transit. If the unit
has been damaged, do not attempt to install or operate
it. File a claim immediately with the carrier, stating
the extent of the damage. Carefully check all envelopes,
shipping labels, and tags before removing or destroying
them.
III. INSTALLATION.
A. General.
Before proceeding, ensure that the lightbar has
been installed on the vehicle roof in accordance with the
instructions packed with the mounting kit. The lightbar is
completely wired at the factory and does not require any
additional internal wiring. All the conductors necessary
for control of any and all basic and optional functions are
contained in the cables. The basic light functions of the unit
must be controlled by a user-supplied control head.
Light system controls must be located so the
VEHICLE and CONTROLS can be operated
safely under all driving conditions.
1. Route the control cable into the vehicle and
near the eventual location of the user-supplied control
head. Route the Red 10 gauge power wire into the vehicle
and to the battery.
2. For proper light operation, the control cable
must be properly terminated inside the user-supplied
control head. Using figure 1 as a guide, make the

Figure 1.
appropriate electrical connections. Ensure that the lines
are adequately fused as shown and that the switch capacity
is adequate for the current requirement.
Reverse polarity may damage any power supply
and prevent operation. Ensure that the correct po-
larity is observed. The positive (+) power lead must
be fused at the source for 40 amps.
3. Connect the separate 10 gauge black lead to
the vehicle ground terminal (-) and separate 10 gauge red
lead to the vehicle battery hot terminal (+).
NOTE
All the lightbar functions can be activated by
applying 12VDC to the appropriate control line.
The 10 gauge black and red power leads must be
connected to their respective battery terminals for
a function check.
B. Function Activation – Excluding SignalMaster™
(see figure1).
1. Mode Inputs.
There are three modes of operation available.
Mode 1 (RED), Mode 2 (ORANGE), and Mode 3 (YELLOW)
each have ten unique programmable flash patterns. One
of the ten available flash patterns can be programmed to
each mode input. Programming will be covered later in this
section. To activate a mode, apply 12VDC to a mode input
wire.
2. Front-light Cut Off.
Applying 12VDC to the front-light cut off
(GREEN) wire will cause the front of the lightbar to cut off.
When the front-light cut off is active, only the rear and rear
portion of the end cap will function.
3. Rear-light Cut Off.
Applying 12VDC to the rear-light cut off
(GREY) wire will cause the rear of the lightbar to cut off.
When the rear-light cut off is active, only the front and
front portion of the end cap will function.
4. Work Lights.
Applying 12VDC to the Work lights (BROWN)
wire will cause the Work lights to illuminate.
5. Right Alley.
Applying 12VDC to the Right Alley (BLUE)
wire will cause the Right Alley lights to illuminate.

V. MAINTENANCE.
Crazing (cracking) of lenses will cause reduced ef-
fectiveness of the light. Do not use cleaning agents
(which will cause crazing) such as strong deter-
gents, solvents, or petroleum products. If crazing of
lenses does occur, reliability of light for emergency
signaling purposes may be reduced until lenses are
replaced.
High voltages are present inside the lightbar. Wait
at least 10 minutes after shutting off the power
before servicing the unit. Disconnect ALL power to
the lightbar before any maintenance is performed.
Failure to do so may result in property damage,
serious injury, or death to you or others.
After prolonged operation, The unit gets hot and
can cause burns. Do not touch the unit while or
shortly after it has been operating. Always allow
the unit to cool before handling.
A. General.
Ordinary cleaning of the plastic lenses can be
accomplished by using mild soap and a soft rag. Should fine
scratches or a haze appear on the lens, they can be removed
with a specialty plastic cleaner/polish such as Plexus® and
a soft cloth. Alternatively, non-abrasive, high-quality, one-
step, automotive past cleaner/wax may be used.
B. Outer Lens Removal (see figure 5).
Remove the end dome, then starting at one end,
pop the bottom of the lens off the lower extrusion. The
preffered method is to apply pressure to the center of the
lens with the thumb of one hand while the fingers of that
hand snap the lens from the extrusion. Alternatively, a
small, flat-bladed screwdriver may be used to carefully pry
the lens from the extrusion, ensuring that the lens and the
underlying o-ring cord are not damaged. Once the end is
free, the lens can be peeled off the bar. To install the lens,
hook the upper edge into its o-ring groove then snap the
lower edge into position. Seal the end of the lens/extrusion
joint with RTV as shown.
C. End Dome Removal and Lamp Service.
1. Removal.
Remove the two 1/4-20 Phillips Flathead
screws retaining the dome assembly. Slide the assembly
away from the bar and unplug the 15-pin electrical
-6-

connector. With the end dome removed from the bar,
remove the 10-32 Phillips head screw from the bottom of
the dome. The lighting units, upper plate, and lower plate
are now removed from the dome as an assembly. Once free
of the dome, the top plate and lighting units lift free from
the lower plate.
2. Installation.
Installation is reverse of disassembly. Inspect
the dome seal for cuts or tears, replacing as necessary
(see paragraph VI. Replacement Parts). Inspect the self-
clinching nuts in the bottom plate to verify that they
are not loose in the plate and that the threads are not
damaged. If either of these conditions exist, replace the
bottom plate assembly (see paragraph VI. Replacement
Parts). When installing the lighting units, pay attention to
the locating slots, tabs, and bosses. The 10-32 Phillips screw
and the two 1/4-20 Phillips flat head screws are coated at
the factory with anti-seize compound to prevent stainless
galling. If the screws are cleaned or replaced apply a
tiny amount of anti-seize (user-supplied – Bostik Never-
Seez© Is a commonly available brand) to the first two or
three threads. Before securing the Phillips head screw
in the bottom of the dome, ensure the holes for the dome
mounting screws are properly aligned in the dome, top
plate, and bottom plate. The dome seal must be compressed
to provide a good seal, thus pressure must be applied
to the dome during installation. A 1/4" drift punch (or a
1/4" shank of a #2 Phillips screwdriver) is used to align
the holes in the dome, top plate, end bracket, and bottom
plate. While keeping slight pressure inward on the dome,
align both holes, leaving the drift in the second hole while
screwing the screw in the first hole. Use due care when
staring the screws to prevent cross-threading. Start both
screws before securing either. Do not over tighten.

D. Halogen Lamp Replacement.
A serious injury may result if the lamp is
touched when hot. Always allow lamp to cool
before removing. Halogen lamps are pressur-
ized and if broken can result in flying glass.
Always wear gloves and eye protection when
handling lamps.
Service life of the lamp will be shortened if the
glass portion is touched. If the glass has been
handled, clean carefully with a grease solvent.
See figure 6. Replace the defective lamp with an
exact replacement only (see paragraph VI. Replacement
Parts).
E. Main Bar Lighting Service (see figure 5).
To remove a complete unit from the main bar,
first remove the outer lens as detailed above. Remove the
retaining clip from both sides of the unit to be removed. A
small flat-bladed screwdriver may be used to release the
tabs of the clip. Slip the unit out of the bar and disconnect
the electrical connector. Installation is the reverse; the clips
snap into position with an audible click.
F. Cleaning Reflector Assemblies.
Use a soft tissue to clean reflectors. Avoid heavy
pressure and the use of caustic, abrasive, or petroleum-base
cleaners, which will scratch or dull the surface.
G. PCB Backer Board Assembly Replacement, Solaris
