your vehicle. Because vehicles can vary widely in their design, it may be
necessary to configure the brackets differently than described. Some
applications may require you to design your own custom brackets. The

washers. Please note that
washer is used as a spacer
on the square neck of the
carriagebolt. Slide the bolt
and washer through the
back of the left bracket.
Be sure to select the correct
bracket. The larger flange

tapping Phillips pan head screws and
use them to install the left attaching
bracket on the light.

to over tighten the screws!!! Over
tightening of the screws can strip the
holes and result in a faulty mount.
3. Once the left attaching bracket is installed
securely on the light, fasten one of the

installed visor clips already located on
the vehicle, in conjunction with the
suction cups or window adhesive
mounts. If you do not have any visor
clips, use theAlternate Mounting
section on the next page.
2. Locate the two visor clips on the vehicle.
The style may vary from vehicle to vehicle.
Some styles use only one screw each,
while others may have more. Verify that
both visor clips are a minimum of 3” from
the center of the window, and a maximum
of 8” from the center.
3. Loosen (or remove if necessary) both visor
clips enough that one of the forked brackets

5. Once the brackets are installed securely under the visor clips or with a suitable
fastener, check to see that the bottom of the light is level front-to-back. If it is
not level, remove the light from the visor clips and carefully bend the forked
brackets as necessary. Reinstall the light and check again for levelness.
Repeat this process until the light is level.

described installation, or may completely lack any visor clips. An alternate
mounting screw hole is provided in the bracket for these situations. This hole
can be used with an appropriate user supplied screw or other suitable fastener.

securely mount the brackets to the roof brace. When selecting a screw, take care to
ensure that it is capable of supporting the weight of the light and it will not penetrate
theroofofthevehicle.
5. Carefully drill any necessary pilot holes in your roof brace. CAUTION: Take care to
ensure when selecting a screw and drilling the hole that it is capable of
supporting the weight of the lightand that it does not penetrate the roof of the
