IMPORTANT! The lightbar should be a minimum of 16” from any
radio antennas!
Permanent Mounting:
1. Locate the mounting foot and mounting plate included with your lightbar. If not
already present, install the plate onto the mounting foot. When properly
positioned, this plate is centered from side to side on the mounting foot.
2. Flip the lightbar upside-down to expose the bottom of the extrusion and place
the mounting foot onto the extrusion.
3. Rotate the mounting foot 90° counter-clockwise. Make sure that the edges of
the mounting foot swing into position under the extrusion mounting lip.
4. Repeat this procedure for the remaining mounting foot and return the lightbar
to its right side-up position.
5. Position the lightbar onto the vehicle roof in the desired mounting location.
One often selected location is directly above the B-pillars. This area is the
strongest part of the roof. Refer to your lightbar manual for your lightbars
cable exit location, to be sure that the lightbar is facing the proper direction.
6. Adjust the two mounting feet outwards so that they are as close to the edge of
the roof as possible. Make sure that both mounting feet are in full contact with
the roof. Be sure that there is no less than 1/2” clearance between the roof
and the lightbar at their closest point. When the mounting feet are in their
proper position, lightly tighten the mounting foot allen head set screws.
7. Turn the lightbar upside down and firmly tighten all of the set screws from step
6 (2 or 4 per side).
8. Note that on the adjustable foot, use the hole in the pad as a guide to drill the two holes into
the mounting foot at the locations shown.
9. Place the lightbar in its final mounting position on the vehicle, mark the mounting hole
locations off onto the mounting surface, remove the lightbar and drill the mounting holes.
10. Place the lightbar back onto the vehicle lined up with the mounting holes and secure the
mounting feet to the vehicle using the supplied hardware.
Slide Bolt Mounting (Permanent):
1. Position the slide bolt mounting plates onto
the bottom of the lightbar extrusion. These
plates rotate into position the same way as
the mounting foot. Position the plates as far
outward as possible (if a 3rd mounting plate is
used, it should be positioned under the center
of the lightbar).
1. Secure the plates to the extrusion using the
set screws provided.
2. Position the lightbar onto the vehicle and
mark the mounting bolt locations. Drill the
necessary mounting holes using an
appropriately sized drill bit sized for a 1/2”
bolt.
NOTE: Model MKAJ is an adjustable mounting foot.
On this model you may loosen the screws on the rear
of the foot and adjust the angle of the lightbar. This
feature can be used if the angle of the roof is not level
with the road.
IMPORTANT: To tighten the leveling screws you must
use a torque wrench set at 35 to 40 ft. lbs.
Temporary Mount (Magnetic, Suction Cup):
WARNING: The use of any magnetically mounted
warning device on the outside of a vehicle in motion is
not recommended and is at the sole risk and responsi-
bility of the user.
Magnetic/suction: Thoroughly clean the mounting sur-
face prior to mounting. For suction cup mounting, wipe the
suction cup clean, place the beacon onto the mounting
surface and apply gentle pressure to ensure a good seal
has been achieved. The Magnetic/Suction Cups mount the
same as standard suction cups but are best suited to a flat,
steel surface.
Magnetic: Place the lightbar onto the mounting surface
and plug it into the vehicle cigar lighter.
