Trouble Shooting

System does not turn “ON”

Check to see that the ribbon cable from the remote

controller is fully inserted into the controller.

Check “Ignition Wire”, make sure it is getting constant 12

volts positive when engine is “ON”.

Check fuse. If fuse looks bent or blown replace with a 5amp

fast acting glass fuse.

Make sure that ribbon cable from remote control is not

pinched or damaged.

LED lightbar does not work.

Check to see that cable between LED lightbar and controller

is not damaged.

Plug into another port to verify that it is the LED lightbar.

A Section of my LED lightbar is not working

Plug LED lightbar into another port to verify that it is the

LED lightbar.

Check to see that all the wires on the LED lightbar connector

are fully inserted into the header.

Features

General

Thank you for purchasing the ULS400 Scanning LED undercar

lighting system from VARAD. To ensure proper use, please read

this manual prior to installation.

The ULS400 demonstrates the innovation and technical abilities

of the engineering team at VARAD. Our latest kit combines superior

functionality with sleek product styling to put your ride at the

forefront of the tuner scene. With 4 low profile LED lightbars,

digital control module and a sleek wired hand-held controller,

you can command cool scanning patterns, strobing action or just

glow.With our patent pending new system configuration, optimum

color bleed is achieved using our latest high flux 70 degree LED’s.

These new high flux LED’s allow us to use fewer LED’s than those

found in typical applications to provide a more uniform and superior

color blend. If you demand the latest in lighting technology,

VARAD will take you there - Enjoy!.

To prevent fire or shock hazard, do not expose the digital controller

to rain or moisture.

To avoid electrical shock, do not open the digital controller. Refer

servicing to a factory authorized dealer.

Replace the fuse only with the type provided in the fuse holder.

Failure to do so can cause malfunction.

Precautions

All “Slave” systems on the network will replicate the “Master”

system in the following way:

Mode 1: Solid.

All networked controllers will change to the master system “ONLY”

after the intensity has been selected.

Mode 2: Patterns/Strobing/Breathing/Comet

All networked controllers will have an initial delay in synchronizing

to the master controller.

Mode 3: Music Reactor.

All networked units will react in sync with the master controller.

To exit set up mode - Push and hold button until

all LED’s turn “OFF”.

Network mode is now “Active”.

Step 4:

Push button once to turn LED no.4 “ON”.

Each ULS400C controller features a built in“network ready”feature.

This feature allows multiple kits to be installed at the same time

on large vehicles such as SUV’s, Limousines, Semi’s, RV’s and Marine

applications. To activate this feature simply connect the white

wire of all digital controllers together during installation and set

up the master as shown below.

Setting up the “Master” controller.

Installation notes!

Only one wired remote control needed. The digital controller

with the wired remote controller will be designated “Master”.

Only the “Master” unit requires hook up of the music input wire

(Blue wire).

All controllers must have ground wire, positive wire and ignition

wire connected at the same location. This will ensure best network

communication.

All controllers must have their own fuse. Do not use one fuse for

all systems!

Turn ignition “OFF”

Push and hold button until LED no.1 is “ON”.

(release button after LED turns “ON”).

Wiring Schematic

See “Wiring Schematic Continued Page 9”

Front of vehicle

• There are no specific plug

locations for plugging in the LED

light bars.

Install the Digital Controller inside the vehicle. Find a location

that will allow all the wires to the LED lightbars to connect

without binding. The location should be 36” from where you

decide to install the wired remote control. The wired remote

control should be installed in a location within reach of the

driver.

Installation of Controllers

Wiring schematic

Wiring Schematic Continued

Connect wiring harness as indicated below:

• Red wire - Battery Positive

• Black wire - Negative (ground)

• Yellow wire - Ignition (+12v when ignition is “ON”)

• Blue wire - Positive speaker terminal

• White wire - Network (See “Networking pg 14”)

When all controllers and LED lightbars are installed you can

proceed to plug all connectors into the ULS400C controller.

Proceed to the “Operation of ULS400” section.

Visually inspect underneath your vehicle to determine a suitable

location for mounting each LED lightbar. Hold the LED lightbar

up in the prospective mounting location to verify that it will not

interfere with existing parts under the vehicle. For the 48.5”

lightbars it is important that the wire leads face the same

direction (front or rear) to ensure symmetry of the Scanning

patterns.When you have found a suitable location, begin to

install the mounting clamps. There are 4 clamps for each side

lightbar and 2 for each front and rear lightbar. Space each clamp

approximately 1 foot between each other. It is important to

install all mounting clamps in a straight line. It helps to use a

reference point on the chassis such as the pinch weld seam, etc.

Mark each drilling point and pre-drill each hole with a 1/8” drill

bit. Install all clamps facing the same direction. Now hold the

lightbar up and install a tie strap through the clamp at each

mounting point. Trim excess tie strap material. Repeat the

process for each lightbar.

section of the LED lightbar.

The remote control will flash a Scanning pattern when ignition is

turned off. The Scanning pattern cannot be changed.

ULS400RC - Visual Theft Deterrent

Operation of ULS400

The ULS400 is operated with a single button remote control. All

features can be controlled by three types of button operations:

• “Push and Hold” (greater than 1 second) to change modes.

• “Push and release” (momentary) to change features in

selected mode.

• “Double click” to change speeds (Mode 2 only)

For example:

To turn system “ON”

Push and hold button until Mode 1 LED is active. The system will

power up and go into Mode 1 (Solid Glow). The default intensity

is level 4 (Maximum brightness). Each momentary push of the

button will change the intensity level. Refer to “Mode Operation

Flow Chart” for more details.

There are three modes of operation:

Mode 1 - Solid Glow

Mode 2 - Scanning patterns/strobe/Breathing/Comet

Mode 3 - Music Reactor

Refer to “Mode Features” on page 13 for details on features for

each mode.

Turning system “OFF”

To turn the system “off” quickly, push and hold button until all

lights on the remote control turn “off”.This will take a few

seconds only.
