Mounting the Lightbar on the Vehicle
HEAVY ObJECt—Use lifting aids and proper lifting techniques when removing or
replacing this product. Failure to follow this warning may cause personal injury.
IMPORTANT: Plan all cable routing before completing the installation.
To mount the lightbar:
1. Place the lightbar assembly on the vehicle roof at the selected location. Typically, the lightbar should be
installed so that the mounting hooks attach at, or immediately behind, the door center post.
2. Adjust both mounting bracket assemblies 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 lightbar assembly so that the end of the
assembly and the edge of the roof are equidistant on each side of the vehicle.
3. Check to ensure that the lightbar is level. If it is not level, make adjustments by rotating the lightbar in
the mounting bracket slots or raising or lowering the ends of the lightbar. Tighten all eight 5/16" ToRx
head bolts that fasten the mounting feet to the mounting brackets.
IMPORTANT: To maximize aerodynamic efficiency and high-speed stability, it is recommended that
the lightbar be mounted with a one-inch or greater gap between the bottom edge of the lightbar and the
roof. on a high-crowned roof, one inch may not be possible. In this case, adjust the lightbar as high as
possible. Adjust the mounting feet on the mounting bracket as needed.
4. Remove the lightbar assembly from the vehicle roof and place it on soft rags or cardboard to avoid
marring the plastic domes. Turn the lightbar assembly over so that the bottom of the lightbar faces up.
5. Secure the mounting assembly to the lightbar using the eight #10 hex head thread-forming screws.
Tighten the 3/8"-16 hex nuts (two on each mounting bracket) installed in step 7 in "Preparing the
Lightbar" on page 2.
6. Press a vinyl cap plug on each of the four carriage bolts (Figure 4 on page 4).
7. Place the lightbar assembly on the vehicle's roof in the selected position.
8. To fasten the mounting hook and complete the installation, refer to the hook hardware kit instructions
(Federal Signal Part No. 2562480) that is included in the kit.
9. For instructions for the electrical installation, see the Installation and Maintenance Instructions included
with the Arjent lightbar.
10. After the electrical installation, test the lightbar for proper operation as well as the emergency warning
system to ensure that it is operating properly. See the next two sections starting on page 6 for warnings
