SAFETY MESSAGETO INSTALLERS
OF
FEDERAL SIGNAL LIGHT SYSTEMS
WARNING
People’s lives depend on your safe instal-
lation of our products. It is important to
read, understand and follow all instruc-
tions shipped with the products. In
addition, listed below are some other
important safety instructions and pre-
cautions you should follow:
• To properly install a light assembly:
you must have a good understanding
of automotive electrical procedures
and systems, along with proficiency
in the installation and use of safety
warning equipment.
• When drilling into a vehicle struc-
ture, be sure that both sides of the
surface are clear of anything that
could be damaged.
• A light system is a high current
device. In order for it to function
properly, a separate ground connec-
tion 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 effective ground path as long as
the light system is to be used.
• Locate light system controls so the
VEHICLE and CONTROLS can be
operated safely under all driving
conditions.
• This product contains high intensity
LED devices. To prevent eye damage,
DO NOT stare into the light beam at
close range.
• You should frequently inspect the
light system to ensure that it is
operating properly and that it is
securely 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. UNPACKING.
After unpacking the Vista lightbar, inspect it for
damage that may have occurred in transit. If the unit
has been damaged, file a claim immediately with the
carrier, stating the extent of damage. Carefully check
all envelopes, shipping labels and tags before remov-
ing or destroying them.
II. INSTALLATION.
A. General.
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 cable.
The basic light functions of the unit must
be controlled by a user-supplied control head.
Before proceeding, ensure that the lightbar
has been installed on the vehicle roof in accordance
with the instructions packed with the mounting kit.
WARNING
Light system controls must be located so
that VEHICLE and CONTROLS can be
operated safely under all driving condi-
tions.
1. Route the control cable into the vehicle
and under the dash, near the eventual location of the
user-supplied control head.
2. For proper light operation, the control
cable must be properly terminated inside the user-
supplied control head. Using figure 1 and table 1 as a
guide, make the appropriate electrical connections.
Ensure that the lines are adequately fused as shown,
and that switch capacity is adequate for the current
requirement.

CAUTION
Reverse polarity may damage the power
supply and prevent operation. Ensure that
correct polarity is observed.
3. Connect the separate 8 gauge black
lead to the vehicle battery ground (-) terminal.
NOTE
All of the lightbar functions can be activated
by applying 12VDC to the appropriate control
line. The heavy black lead (-) must be con-
nected to battery ground, to perform a func-
tion check.
B. Antenna Bracket Installation.
The following is applicable to lightbars that
require an antenna bracket. Before installing the
lightbar on vehicle, the antenna bracket must be
mounted to the underside of lightbar.
See figure 1 and proceed as follows:
NOTE
When turning the lightbar over, use caution
to avoid damaging the lightbar domes.
1. Remove and retain the supplied nut and
lockwasher from the underside of the lightbar.
2. Position the bolt in the center of the
lightbar. Ensure that the area indicated is free from
oil and dirt.
3. Remove the liner from the double stick
tape (affixed to the bracket) and mount the bracket to
the lightbar.
4. Using the previously removed hardware,
secure the bracket to the lightbar. Refer to the
instructions included with the antenna for proper
installation.
C. Function Activation – Strobes.
1. Mode inputs.
There are three prioritized modes of
operation available, with mode three being the
highest priority. Mode 3(WHT/BLU) will override
Mode 2(WHT/YEL) and Mode 2 will override Mode
1(WHT/GREY). One of the eight available flash
patterns can be programmed to each mode input.
Figure 1.
Default configuration is Mode 3 Random Flash, Mode
2 Action Flash and Mode 1 Quad Flash. Program-
ming will be covered later in this section. To activate
a mode, apply 12VDC to a mode input wire. See
figure 2 for proper fusing.
2. Low Power.
The intensity of the strobe tubes can be
reduced by approximately 50% by applying 12VDC to
the Low Power (WHT/ORG) wire. See figure 2 for
proper fusing.
3. Cutoff.
Main power to the strobe power supplies
is supplied via separate wires, (RED Front) and
(WHT/RED Rear). Front or Rear cutoff can be imple-
mented by removing power from the appropriate
wire.
CAUTION
When programming ensure that power (RED
& WHT/RED) is supplied to both front and
rear power supplies. Failure to do so will
cause front and rear strobes to operate with
different flash patterns.
4. Programming
Each of the three modes of operation can
be programmed to operate with one of the eight
available flash patterns listed below:

• 3 – Random
• 4 - Triple
• 5 – Fast Quad
• 6 – Penta Flash
• 7 – Quad/Action
• 8 – Fast Action
To program, apply 12VDC to the mode
input to be programmed. Ensure that both the front
and rear strobes are flashing. Apply 12VDC to the
programming (WHT/BRN) wire. Strobes will stop
flashing for approximately 2 seconds and then
advance to the next flash pattern and begin to flash.
If the strobes do not flash you are at the null point.
The selected pattern will be stored in memory and
will be selected the next time that mode is selected.
Every time power is reapplied to the programming
input, it will advance to the next flash pattern. To
program the other mode inputs, apply 12VDC to the
desired one and repeat the above operation. When
programming is completed ensure that 12VDC is
removed from the programming wire.
D. Function Activation - Lower Level LED’s.
1. Front LED’s/Flasher.
To activate front LED flasher apply 12VDC to
the Blue wire. See figure 2 for proper fusing.
2. Rear LED’s/Flasher.
To activate rear LED flasher apply
12VDC to the Violet wire. See figure 2 for proper
fusing.
3. Backup Operation.
To activate the backup activation for both
front and rear LED flashers apply 12VDC to the
WHT/VIO wire. See figure 2 for proper fusing.
E. Function Activation – Man Down Blue LED
Module.
1. Activation.
Apply 12VDC to the Gray wire. See figure
2 for proper fusing.
2. Intensity Adjustment.
Remove upper center dome. Apply
12VDC to the Gray wire. Locate the Man Down/
Backup Feed circuit board. Adjust potentiometer R1
clockwise to increase intensity and counter-clockwise
to decrease intensity. Remove 12VDC and reinstall
center dome.
III. BASIC MAINTENANCE.
WARNING
High voltages are present inside the
lightbar. Wait at least ten (10) minutes,
after shutting off power, before servicing
this unit. Failure to do so may result in
property damage, serious injury, or
death to you or others.
Disconnect ALL power to the lightbar before
any maintenance is performed.
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 the domes,
they can ordinarily be removed with a non-abrasive,
high quality automotive paste wax.
WARNING
Crazing (cracking) of domes will cause
reduced effectiveness of light system. Do
not use cleaning agents (which will
cause crazing) such as strong detergents,
solvents, or petroleum products. If
crazing of domes does occur, reliability
of light for emergency warning purposes
may be reduced until domes are re-
placed.
B. Halogen Lamp Replacement.
WARNING
A serious injury may result if lamp is
touched when hot. Always allow 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
Service life of lamp will be shortened if glass
portion is touched. If glass has been handled,
clean carefully with a grease solvent.

C. Cleaning Reflector Assemblies.
Use a soft tissue to clean the reflectors.
Avoid heavy pressure and the use of caustic or
petroleum base solvents which will scratch or dull
the surface.
D. Strobe Tube Replacement.
WARNING
High voltages are present inside the
lightbar. Wait at least ten (10) minutes,
after shutting off power, before servicing
this unit. Failure to do so may result in
property damage, serious injury, or
death to you or others.
Disconnect ALL power to the lightbar before

As strobe lights are used, flash tubes begin
to darken, causing the light output to decrease. Also,
as flash tubes age, they may have a tendency to
misfire (not fire periodically).
After extended operation, occasionally
check for flash tube degradation. Should the tube
misfire, have a noticeable decrease in light output,
glow continuously, or darken excessively, it should be
replaced.
NOTE
Not replacing a strobe tube when any of the
above conditions exist could cause a break-
down of other power supply components.
For Primary Linear Strobe Tube replace-
ment, see figure 4 and proceed as follows:
1. Refer to table 2 for the correct strobe
tube part number.
2. Remove and retain the screw which
secures the defective strobe head assembly to the
dome. Remove and retain the two screws which
secure the lens to the strobe head assembly.
3. Insert a small flat head screwdriver in
the slot on the back of the reflector. Note the strobe
tube’s orientation and gently push forward to release
the defective strobe tube.
