High efficiency LED technology
DIRECTIONS FOR USE
Prior operations
Before using the lights, it is necessary to completely charge their battery. The system is
provided with a NiMH battery pack without the memory effect, therefore it is not
necessary to wait until it is completely run down before recharging it.

ENGLISH
3 - E
To carry out a full battery recharge, follow these instructions:
Connect the power supply cable to the dedicated socket on the left light;
Connect the cable to the cigar lighter socket or to the 230Vac outlet;
The left tail light will be ON indicating that the charge is in progress;
The left tail light will turn OFF when the charge is completed (after about 6
hours);
When the charge is complete, disconnect the charging cable.
When the light set is turned ON (position RADIO or ON) a test of all the lights will be
carried out in sequence to verify that they are working, then the STOP lights will blink
if the available battery charge is between 100% and 60%, the DIRECTION
INDICATORS will blink if the charge is between 60% and 30%, the TAIL lights will
blink if the charge is less than 30%, if only the left TAIL light blinks shortly every 4
seconds then the battery is totally run down and it is best to recharge it.
LIGHTS
External appearance
The lights pair have a magnetic base (with a rubber pad) or a pump suction cup
and a tilt bracket allowing a better directional control. Labels indicate the
installation position and function of each element.
RIGHT LIGHT (RIGHT): in addition to the label, a waterproof 3-position
switch on the back and the connection cable for the left light, characterize the
right light.
LEFT LIGHT (LEFT): has no switch and no cable. A 5-pin connector for the
connection with the right light is present on the back and the magnetic self-
centering charging connector.

ENGLISH
4 - E
Installation
The lights are equipped with a rubber padded magnetic base for the installation on the
vehicle body or a suction cup: for the best performance we recommend to locate it on a
plain and clean surface, especially for the suction cup version.
Each light is provided with a tilt bracket allowing better directional control of the
optical set and a better visibility of the light signals.
WARNING: to remove the lights we suggest that you directly grasp the magnetic base
or the bracket.
Connections
In order to connect the two lights, a cable with an automotive grade, water tight
connector is provided.
To recharge the battery there is a classic plug connector.
Functionality
According to the label next to the switch, the set can work in two different modes
depending on your needs:
8. RADIO Mode: the set repeats the controls that are received from the
paired transmitter. The received functions are: TAIL LIGHTS,
DIRECTION INDICATORS and STOP. After 30 minutes of no
activity the receiver will enter a battery save mode and any command
transmitted will resume normal operation; after 4 hour of no activity
the receiver will enter a sleep mode with a negligible battery drain: it
will be necessary to turn OFF and then turn ON again to resume the
normal operation.
9. ON mode: only the tail lights are ON and the radio link is ignored, the
transmitter can remain connected to the towing vehicle.
Every set includes a paired transmitter, if you need to cancel the receiver’s memory or
pair a new transmitter, please consult the “Transmitter pairing” section in this guide.
WARNING: it is important to switch OFFthe set (switch in the OFF position) when
not in use, this helps to preserve the battery life.

ENGLISH
5 - E
Receiver
The receiver (located in the right light) is a category 2 GFSK PLL receiver in SMT
technology, in compliance with the EN 300 220 European standard. The receiver can
operate on 2 channels to avoid RF disturbances present on the used channel. To allow
the channel change it is necessary to leave ON the vehicle tail lights (in RADIO mode)
to let the receiver and the transmitter to carry on the communication on the alternate
channel.
Lamps indications
The left tail light is also a low battery indicator, when the lights are turned ON, after the
lamp test, if the tail light blinks shortly every 4 seconds then the battery is run down and
must be recharged. If, after the lamp test, the right tail light blinks continuously ON for
2 seconds and OFF for 2 seconds, then there is no paired transmitter in memory. The
only usable mode will be the ON mode. Please, pair a transmitter before using the
RADIO mode (see the “Transmitter pairing” section).
ACQ pushbutton
This is the transmitter pairing and clear memory pushbutton.

TRANSMITTER PAIRING
Every transmitter has a unique code, it is necessary to pair the transmitter with the
receiver, only commands from the recognized transmitter will be executed.
To pair a new transmitter:
Open the right light, without disconnecting the cable;
Connect the transmitter to the vehicle, make sure no other TL-TX transmitter
is transmitting nearby (100m);
Switch ON the vehicle’s tail lights, switch ON thelight setand press the ‘ACQ’
pushbutton on the receiver’s board;
The right tail light will blink, release the pushbutton and turn off the vehicle’s
tail lights;
Activate the vehicle’s lights and verify that the repeated lights are working
correctly.
The procedure is over, the right light can be closed.
If the procedure has not been successful it must be replaced
Should a need arise to clear the transmitter pairing (for example in case of a pairing
error) you can follow this procedure:
Open the right light without disconnecting the cable;
Turn OFF the lights, disconnect any nearby transmitter, press and maintain
pressed the ACQ pushbutton;
Turn ON the lights and wait 10 seconds, the right tail light will blink indicating
that the memory is erased, release the pushbutton.
It is now necessary to pair a transmitter to operate the lights in RADIO mode.

IN CASE OF MALFUNCTION
THE SET IS NOT WORKING:
Do the lights carry out the lamp test?
No:
battery is totally run down, please, recharge it using the dedicated charging
cable.
Yes, and the left tail light blinks every 4 seconds:
battery is very low, recharge it using the dedicated charging cable.
Yes, and the radio commands are not repeated:
-There is no paired transmitter. Follow the “Pairing transmitter” section
to pair one.
-Verify that the switch on the back is in the RADIO position.
-Keep the vehicle tail lights ON: this will allow to carry out the channel
change procedure in the event that a radio disturbance is present on the
actual channel.
Yes, and the right tail light is blinking 2 seconds ON, 2 seconds OFF:
Pairing memory is empty. Follow the “Pairing transmitter” section and pair a
transmitter
THE LIGHTS ONLY RECEIVE CONTROLS FROM A SHORT DISTANCE:
Transmitted signals are not stable:
make sure that the transmitter is not surrounded by metallic structures.

TRANSMITTER
TL-TX PLL TECHNOLOGY
CHARACTERISTICS OF THE TRANSMITTER
The transmitter TL-TX PLL TECHNOLOGY derives from a consolidated experience in the
radio controls sector: it is conceived to control the TL-RX repetitive lights system.
Here are the main characteristics:
Dedicated versions for 12V or 24V
Modulation: GFSK
High transmission stability
ISO1185 e ISO1724 connections available
Transmission-in-progress LED indicator
Polyurethane resin potted electronic board for better protection
In compliance with the EN 300 220 European standard
DIRECTIONS FOR USE
Activating the transmitter
To activate the transmitter and make it operational, it is only necessary to plug it in the
dedicated socket at the back of the towing vehicle. The transmitter works powered by
the lights control voltage on the socket pins.

ENGLISH

Connections details
The transmitter is available in two models that operate at 12V or 24V with different
kinds of socket on the towing vehicle.
o12V model
FUNCTIONS:
1. LEFT direction indicator
2. ANTI-FOG light
3. GND connection
4. RIGHT direction indicator
5. RIGHT tail light
6. STOP lights
7. LEFT tail light
oModello 24V
FUNCTIONS:
1. GND connection
2. LEFT tail light
3. LEFT direction indicator
4. STOP lights
5. RIGHT direction indicator
6. RIGHT tail light
7. Trailer braking control
Only some of the contacts are transmitted; yet, we kindly suggest that you verify
the correspondence of all the poles on the vehicle.
Use of the Transmitter
Once the transmitter is inserted in the specific socket (at the back of the towing vehicle),
it is operational and it carries out a transmission every time it receives a signal that has
to be repeated (STOP, TAIL and DIRECTION INDICATORS).
The transmission is signaled through the blinking blue LED at the back of the
transmitter.
