How to program the single headlight feature for “tailing” a vehicle
Pushbuttons:
FISOS has three waterproof pushbuttons. The left button is the multi-purpose button, the middle is the
scroll down button and the right is the scroll up button. Manipulating these buttons in a particular sequence is
what allows you to access the multiple features of this module.
Flash Pattern Selection:
Selecting a flash pattern is easy. With the module oriented with the buttons on the bottom row, pressing
either the center or right buttons will scroll down or up through the flash pattern list. Each pattern can then be
manipulated for a more custom effect.
Flash Pattern Manipulation:
When you find your desired flash pattern, you can then change the speed and pulse count for that
pattern.
To change whether the flash pattern will display a single, double or even more pulses per headlight,
simply press and hold the center and right buttons (scroll down and up). While holding these buttons down,
press and release the left program button the number of times you wish for the headlights to illuminate. The
headlights will flash each time the button is pressed. When you are done, release all the buttons.
To change the speed of the flash rate, simple press and hold down the left program button and use either
the scroll down or up buttons to slow down or speed up the flash pattern. The new effect will display when all
buttons are released.

When manipulating the variable speed patterns (patterns 5-10), you can adjust the slow side of the flash
pattern. This means you are able to adjust how long it takes to reach the peak of the pattern before it returns to
the bottom of the flash rate.
There are a total of 14 base flash patterns to choose from. Each pattern can be manipulated, giving you
the option of literally hundreds of available patterns. To reset any given flash pattern to its default setting, hold
down the program button followed by the scroll down and then scroll up buttons. Release all buttons to restore
the original flash rate.
Nighttime Override Feature:
In certain states, headlight flashers are not allowed to be used at night. If your FISOS was not ordered
pre-programmed for your desired application, then you can easily activate/deactivate this feature after the
product has been installed.
Non-DRL Version:
If your flasher was made for vehicles with no daytime running lights, simply turn on your headlights and
FISOS. To activate the nighttime cutoff, simply press the left program button on the FISOS module. Your
flasher will turn off, giving you normal operation of your headlights at night.
To deactivate the nighttime cutoff, follow the same instructions above. FISOS will resume flashing.
DRL Version:
If your flasher was made for vehicles with daytime running lights, make sure FISOS’s WHITE wire is
connected to your vehicle’s parking lights. Turn on your parking lights and follow the instructions from above
for turning on or off the nighttime cutoff feature.
Surveillance Mode:
Your FISOS module has been programmed with a unique feature. This feature provides the ability to
disable the activation of one of your headlights. The purpose of this feature is to allow an officer the ability to
discretely “follow” a suspect vehicle and give the appearance of being two separate vehicles when tailing
someone at night.
To activate this feature, supply +12 volts through a user provided switch to the BLACK wire on this
module. When the headlights are turned on and the BLACK wire has +12 volts, one headlight will turn off.
To swap which headlight will be off, simply push the left program button while this feature is on and the
headlights are on. The deactivated headlight will turn back on and the opposite headlight will turn off.
FISOS is preprogrammed to have the passenger’s side headlight turned off upon activation of this mode,
giving the driver more road illumination in front of him/her. You may change it to your liking after installing it.

One-Touch Deactivation/Activation:
If you ever need to turn off your headlight flasher when it is activated, all you need to do is use your
Flash-to-Pass switch. One pulse of your switch within two seconds will turn off the flasher. One more pulse
within two seconds will reactivate the flasher. Multiple pulses do not trigger this feature, only a single pulse
within two seconds.
You no longer need a dedicated switch to deactivate your headlight flasher or turn off a group of lights
like your grille lights should the trigger wire share the same supply.
Why might you need this feature? This will be useful when responding in fog at night, when on-scene
or even driving through kicked up dust on dirt roads, which makes driving more difficult.
Finishing the Install:
After everything has been installed, we recommend protecting these cables by enclosing them in wire
loom and securing them in place using wire ties. This preserves your equipment for longer trouble-free service.
Testing:
After all connections have been made, you may test the operation of the low beam and high beam
system as well as the headlight flasher and override system. With FISOS turned off, by activating your low
beams and high beams, your headlights should operate normally.
Next, activate FISOS. Your headlights should be flashing to the selected pattern. With your headlights
flashing, activate your Flash-to-Pass switch. FISOS should stop flashing and your headlights should return to
normal operation, turning on and off with every pull of the FTP switch. FISOS will resume control in two
seconds.
