The Split Phantom™is designed to be mounted on the inside
of your vehicle. It is not intended for exterior applications and is
not warranted against water damage.
It is the sole responsibility of the owner to ensure the warning light is
secure. Check your light every time you enter the vehicleto ensure that
it is mounted securely. The manufacturer assumes no responsibility for
the secure mounting of this light.
The following mounting instructions describe the standard, most
common way to mount this light. This method may or may not apply to
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
installer assumes all responsibility for the integrity of the installation. It is
the sole responsibility of the owner to ensure the light is secure.
Mounting Instructions
Before installing any of the
brackets, slide the enclosed
rubber channel over the
frontedgeofthebaffle .
The ULB21 is designed to be mounted in the front windshield of a vehicle using
both of the pre-existing visor clips. An alternate method is also shown using the
Universal Brackets.

UNIVERSAL BRACKET INSTALLATION
(Model 274-ULB21-U1)
•The Universal Mount use two forked brackets and either a pair of suction
cups or a pair of window adhesive mounting pads (both included).
•The Forked Bracketsmust be installed for both the suction cup and
window adhesive mounts.
•Determine if you can install the Forked Brackets under your visor clips or
if you need to attach them in an alternate fashion and refer to the
appropriate section on pages 6 or 7.
The mounting instructions are divided into two separate sections. If you
are using the Universal Mount, proceed below. If you will be using one of
the vehicle specific brackets, please skip to page 9.

-5-
CAUTION: Take extreme caution not to over tighten the screws!!! Over
tightening of the screws can strip the holes.
1. Insert one of the carriage
bolts through one of 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
should be located towards
the center of the light.
2. Remove three of the #8 x 1/2" self-
tapping Phillips pan head screws and
use them to install the left attaching
bracket on the light.
CAUTION: Take extreme caution not
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
forked “L” brackets to the attaching
bracket, using the carriage bolt,
a washer, and a nut. Leave
the nut slightly loose to
allow for minor adjustments
during the remainder of the
installation.
Attach Forked Brackets to Light
4. Repeat steps 1-3 for the right attaching bracket .

1. Standard mounting uses the factory
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
caneasilyslideundereachofthem.
4. Slide one forked bracket under each visor clip
and tighten the clip such that it securely holds
eachbracketinplace.
Bend here if
necessary
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.
Attach Forked Brackets to Visor Clips
(If you do not have visor clips, or your visor clips will NOT provide a secure mount, or this
method will not work in your vehicle for any other reason, use the alternate method on the
next page.)

Attach Forked Brackets using Alternate Method
If you are not using the visor clip installation described on the previous page,
continue below.
1. Some vehicles may not have visor clips appropriate for the previously
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.
2. If you are using the alternate mounting screw hole, you will need to locate the roof
brace under the headliner of the vehicle.
3. Once you have located the roof brace, pick an area to mount the brackets (one on
eachside)thatisaminimumof 3” from the center of your window andamaximum
of 8”.
4. You must then determine an appropriate size screw to penetrate the headliner and
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
vehicle.
6. Install the screws through each bracket.
7. If necessary, adjust your light as described in Step 5 on the previous page.

along with the washers and nylon spacers.
3. Then use the appropriate hardware (as shown above) to attach either the
Adhesive Pads or the Suction Cups, depending upon your application.
If using the window adhesive:
•Be sure to use the tube of cleaner to clean both surfaces.
•After applying adhesive, please allow a minimum of 2-5 minutes
for the pad to adhere to the window before releasing pressure.

Operating Instructions
The Split Phantom™is designed for simple operation using two switches. It
has a 3-Way Illuminated Mode Switch and a Pattern Select/Burst Mode Button.
The 3-Way Mode Switch (Flashing/Off/Steady or Pursuit/Off/Takedown)
This switch is located closest to the driver's side. It is used to select which
mode The Split Phantom™will operate in. While in the Steady (Takedown)
mode, the LEDs will not flash, but instead will remain lit, similar to Takedown
lights. Under the Flashing (Pursuit) mode, the LEDs will flash according to the
pattern you have selected (SeeFlashing (Pursuit) Mode below).
Indicator LED
Located on the bottom of the right half (passenger side) of theSplit
Phantom™is an Indicator LED. When your light is activated in any mode, this
LED will light up.
Pattern Select/Burst Mode Button
Thebuttonlocated on theinsideedgeof the passengerhalf(seediagram above) is
the Pattern Select/Burst Mode button. This is a momentary switch and has two
different functions, depending upon which mode the 3-Way Mode Switch is in.
3-WayMode Switchsetfor Steady(Takedown) Mode:
Ifthe3-way mode switch of your Split Phantom™is in the Steady Mode position,
the Pattern Select/Burst Mode will “burst” your LEDs into a super-bright,high-power
mode (takedowns). This mode will activate for approximately 30 seconds then revert
to the standard steady burn mode. PleaseNote: Immediately after the 30 second
“BurstMode”has ended, thelightwillbe “locked out”ofBurstMode for 30seconds.
3-Way Mode Switch set for Flashing (Pursuit) Mode:
If the 3-way mode switch of your Split Phantom™is in the Flashing Mode
position, the Pattern Select/Burst Mode will act as the Pattern Select button.
Each time this switch-button is depressed, theSplit Phantom will cycle to the
next pattern. The Split Phantom is designed with thirty-five different patterns
(see next page):
Pattern Select / Burst Mode
