I. GENERAL.
This instruction sheet provides directions for
installation of the Federal Raydian™ series warning
system on a vehicle roof. A vehicle-specific mounting
hook is purchased separately and is required to complete the warning system installation.
II. UNPACKING.
The Raydian lightbar has the mounting brackets pre-positioned for mounting on the Ford
Crown Victoria. If the light assembly will be
mounted on a Crown Victoria, skip steps A and
C.
A. Loosen the 3/8-16 hex nuts sufficiently to allow
the mounting brackets to be adjusted in and out to fit
the roof of the vehicle. If the Raydian is being installed
on a vehicle with a steep forward slope roof, like the
Chevy Impala, install the wedges between the HotFoot
and the bottom extrusion of the lightbar on the forward
track as shown in figures 1 and 2.
B. Place the Raydian lightbar on the vehicle roof at
the desired location. Usually the unit should be installed so that the mounting hooks attach at, or immediately behind, the door center post.
C. Adjust both mounting brackets in or out until
the rubber mounting pads rest near the edge of the roof,
or gutter, where the roof is most rigid. Center the unit so
that the end of the assembly and edge of the roof are
equidistant on each side of the vehicle.
IMPORTANT
After unpacking the light bar, carefully check all
envelopes, shipping labels, and tags before removing or
Plan all cable routing before completing the
installation.

VI. BASIC MAINTENANCE.
A. Cleaning the Plastic Domes.
Ordinary cleaning of the plastic domes can be
accomplished by using mild soap and a soft rag. Should
fine scratches or a haze appear on a lens, they can best
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.
CAUTION
The use of other materials such as strong
detergents, solvents, petroleum products, etc.can
cause crazing (cracking) of the plastic domes.
B. Halogen Lamp Replacement.
WARNING
6. Remove the lamp from the housing and
disconnect it from the lamp connector.
7. Insert the new lamp into connector and
reassemble in the reverse order.
NOTE
To reinstall the lamp-retaining ring, insert one
end of the ring into the groove. Press down
around the circumference until the ring is
inserted into the groove.
C. Replacement Parts.

A serious injury may result if the lamp is
touched when hot. Always allow the lamp
to cool before removing. Halogen lamps
are pressurized and if broken can result in
flying glass. Always wear gloves and eye
protection when handling the lamps.
CAUTION

glass bulb portion is touched. If the glass bulb
has been handled, clean carefully with a grease
solvent.
