HEAVY OBJECT: Use lifting aids and proper lifting technique when removing or replacing this
product. Failure to follow this warning may cause personal injury.
NOTE: To aim the optional LED takedown lights to the 45 degree or 90 degree position (+/– 10 degrees),
move the lights to the top of the mounting feet before the installation. See “Aiming the Optional HotFoot
LED Takedown Lights” on page 6.
Installing the Service Kit Mounting Feet
ENSURE PROPER INSTALLATION OF THE MOUNTING FEET: Note that the LH mounting foot is
for the left side of the light bar, and RH mounting foot is for the right side. Failure to follow this
precaution may damage the light bar.
The Service Kit requires that you assemble the mounting feet on the light bar. If you are installing a
new light bar that is shipped with the mounting feet already attached, see “Installing the Adjustable
Foot Brackets” on page 4. New light bars may require that you loosen the 3/8-16 nuts to adjust the
positions of the mounting feet on the vehicle roof.
To install the Service Kit mounting feet:
1. To avoid marring the plastic domes, invert the light bar on soft rags or cardboard.
2. Use the four 3/8-16 nuts and lockwashers to install a mounting foot assembly and a hook-attach
bracket on the light bar. See Figure 1. Tighten the nuts only enough to hold the mounting foot
assembly in place.

Installing the Adjustable Foot Brackets
ROOF SUPPORT STRUCTURE: There is a roof support member that spans the distance between
the driver and passenger side. DO NOT DRILL THROUGH THIS MEMBER! Adjust any hole
locations until the holes can be drilled without going through this member. Failure to follow this
warning will weaken the roof of the vehicle and may lead to an increased chance of bodily injury
or death in a rollover accident.
ENSURE PROPER INSTALLATION OF MOUNTING FEET: Note that the LH Mounting Foot is for
the left side of the light bar, and the RH Mounting Foot is for the right side. Failure to follow this
precaution may damage the light bar.
DRILLING PRECAUTIONS: Before drilling holes, check the area into which you plan to drill to
ensure that you do not damage vehicle components. All drilled holes should be deburred and all
sharp edges should be smoothed. All wires going through drilled holes should be protected by
a grommet or convolute/split-loom tubing.
IMPORTANT: Plan all cable routing before completing the installation. Plan the location of the wire
routing hole in the vehicle roof so that the power and communication cables do not have tight bends and
have some slack to allow disconnection on removal.
The adjustable foot brackets enable you mount the Vision SLR at the maximum height and to level the
light bar.
To install the brackets:
1. To avoid marring the plastic domes, invert the light bar on soft rags or cardboard.
2. Use the 5/16-18 pan Torx screws, 5/16-inch flat washers, and 5/16-inch lockwashers to install the
adjustable foot brackets on the mounting feet. See Figure 3.

3. To achieve the maximum mounting height of the light bar, position the screws in the adjustable
foot brackets at the bottom of the slots. Tighten the screws only enough to hold the adjustable foot
brackets in place.
4. Install the rubber mounting pads to the adjustable feet as shown in Figure 3.
5. To continue with the installation, see “Preparing the Vision SLR for Hook-Mounting.”
Preparing the Vision SLR for Hook-Mounting
To prepare the light bar for hook-mounting:
1. Place the light bar assembly on the vehicle roof at the selected location. The assembly is usually
installed so that the mounting hooks attach at, or immediately behind, the door center post. Before
proceeding, refer to the instructions provided with the separately purchased mounting hook kit.
2. Adjust both mounting foot assemblies in or out until the mounting pads rest near the edge of the roof
or gutter where the roof is the most rigid.
3. Center the light bar assembly so that the end of the assembly and edge of the roof are equidistant
on each side of the vehicle. Ensure that the gutter hooks, when installed, do not interfere with the
door or door glass. Improper clamping on the vehicle roof may result if the gutter hooks contact the
mounting feet. Adjust the mounting feet, if required, before tightening the 3/8-16 hex nuts.
4. Remove the light bar assembly from the vehicle roof and place it on soft rags or cardboard to avoid
marring the plastic domes.
5. Turn the light bar assembly over so that the bottom faces up. Tighten the eight 3/8-16 nuts (four on
each mounting foot) installed in “Installing the Service Kit Mounting Feet” on page 2

Hook-Mounting the Vision SLR on the Vehicle
To mount the light bar on the vehicle:
1. Place the light bar assembly back into its original position on the vehicle roof.
2. To maximize aerodynamic eciency, it is recommended that the lighting system be mounted as high
as possible. Adjust the adjustable foot brackets on the mounting feet as required. See Figure 4.

3. For proper drainage, tilt the nose of the light bar downward approximately 1/8 inch to 1/4 inch while
ensuring the light bar is level from side to side.
4. Using the holes that are most closely aligned between the 5/16-inch pan head Torx®screws, install a
#10 Type B Torx pan head screw to lock in the adjustment. See Figure 4. Minor adjustment may be
necessary. Repeat this step for all four adjustable foot brackets.
5. Tighten all eight 5/16-inch Torx pan head screws that fasten the adjustable foot brackets to the
mounting feet.
6. To fasten the mounting hook, refer to the keeper plate instructions (Federal Signal Part No. 2561635)
included in the supplied Keeper Plate Kit.
IMPORTANT: Frequently inspect the light bar assembly to ensure that all fasteners and brackets are
tight.
Aiming the Optional HotFoot LED Takedown Lights
The optional HotFoot LED takedown lights are factory-wired and installed on the bottom of the mounting
foot. Beneath the mounting foot the aim of the lights is horizontally adjustable +/– 10 degrees.
To aim the takedown lights to the 45 degree or 90 degree position (+/– 10 degrees), move the lights to the
top of the mounting feet before the installation. See “Inverting and Aiming a Takedown Light Above the
Mounting Foot.”
Aiming a Takedown Light Beneath the Mounting Foot
To adjust the horizontal aim (+/– 10 degrees) of the takedown light:
1. Loosen the 10-32 pan Torx screws as shown in Figure 5.
2. Reposition the light and tighten the screws.
