INTRODUCTION
Thank you for purchasing our bSeen product.
bSeen is an indicator light kit developed for electric scooters, electric
bicycles and any other vehicle that lacks of indicators, and light warning
systems.
Sold as a “do it yourself” kit, bSeen is a powerful and reliable system,
based on the latest technologies.
Inside bSeen there’s a powerful 12V pack which guarantee bSeen’s
performance for long periods of time.
At the heart of the system, a micro-controller was programmed for the
most basic tasks, such as right and left turn, and other functions such as
auxiliary head lights control, tail light and hazard warning lights.
bSeen LED units are extremely bright, and can be seen during the day.
LED units are manufactured in-house and carefully inspected to ensure
their waterproof properties.
bSeen handlebar switch unit is easy to operate, with all controls you need
to control the indicator system.!

ECU CONTROL UNIT - INSIDE LOOK
The ECU is the “brain” of bSeen’s system. Inside the ECU there’s a 12V
Samsung battery pack with three 18650 batteries in series, with a total
current output of 3000mAh (3A). To manage the charge and the discharge
cycles, the battery pack is monitored by an electronic balance
management circuit, which guarantees the batteries’ performance. The
balancing management circuit is rated to 20A, with enough margin to
manage the 3A output current from the battery pack.
bSeen’s electronic circuit has protections against short circuits. Three layers
of protection were developed to ensure the batteries stay safe from any
problem that can arise from a short circuit. There’s are also internal quick
blow fuses for LED units and charger port, in case that any overload occurs.
To control the functions provided by the handlebar switch unit, inside
bSeen there’s a pre-programmed micro-controller.
To provide power to the LED units, each LED unit’s output from the ECU is
driven by a transistor, ensuring each LED’s high brightness at all times.
WARNING
The ECU contains micro electronics and it’s powered by a 12V li-ion
battery pack. Li-ion batteries are extremely dangerous if not handled
with care.
The li-ion battery pack inside bSeen’s ECU takes about 80% of the
internal ECU’s room, so please keep in mind:
•DO NOT open the ECU
•DO NOT drill the ECU
•DO NOT put the ECU under any sort of pressure
•DO NOT expose the ECU to direct sunlight during long periods of
time.
•DO NOT expose the ECU to extreme heat

Outside the ECU control unit, you will find:
1 x Charging Port
1 x ON/OFF Switch
1 x Cable tail with a mini connector for the tail LED unit (bSeen standard
version only)
2 x Cable tails with mini connectors for the REAR indicators (L&R)
2 x Cable tails with mini connectors for the FRONT indicators (L&R)

ECU CONTROL UNIT - HOW TO CHARGE
ECU CONTROL UNIT - POWER SUPPLY
Your bSeen kit is supplied with a PSU (Power Supply Unit) especially
designed to charge 12V li-ion battery packs.
On bSeen’s PSU there is a LED monitor, and at the end of the cable there is
an aviation 2 PIN connector.
!
USE ONLY BSEEN PSU TO CHARGE YOUR ECU
The PSU’s electronic circuit detects the existing battery pack’s voltage (V)
and current (mAh), and automatically manages the charging current
until the battery pack is completely charged.
PSU’s voltage and current outputs are specific to comply with 18650’s
safety charging requirements.

ECU - CHARGING PORT
On the top of bSeen’s ECU there’s a waterproof protected connector.
Opening the protection cap will reveal the 2 pin aviation male connector.
Without plugging the PSU to the mains (110V-240V):
• Switch the ECU OFF
• Plug the 2 pin aviation connector from the PSU to the charging port on
the ECU (please note that you need to align both connectors’ guide
slots in order to plug both connectors).
• Switch the ECU ON. If the battery pack still have charge, the LED
monitor on the PSU will light up green. If the battery pack is
discharged, the LED monitor won’t light up.
• Plug the PSU to the mains (110V-240V).
• While charging, the monitor LED will light up red.
• Once the charging cycle is completed, the LED monitor will turn
green.
• Unplug the PSU from the mains (110V-220V).
• Unplug the 2 pin aviation connector from the ECU’s charging port.
Charging times will differ depending on how much charge is left in the
battery pack.
If the battery pack is fully discharged, the time to fully charge is around 2
hours.

CONNECTIONS
HANDLEBAR SWITCH UNIT CONNECTION
The handlebar switch unit it’s fitted with a 2 metres length control cable.
At the end of the cable there’s a green 5 pin waterproof connector. This
connector will plug directly onto the ECU’s handlebar switch connector:
On each connector’s enclosure, there’s a printed arrow. Once both arrows
are aligned, push both connectors against each other until they are fully
sealed.
CAUTION
Please make sure that the ECU is switched OFF before proceed with
any connections.

LED UNITS - OVERVIEW
Each LED unit is supplied with a 1.5 metres length power cable. The LED
unit’s power cable doesn’t have any connector at the end, so that can be
cut to size.
The power cable is a two core “figure of 8” type with polarity.
To blend with most vehicles, the two cores are black, however, there are 3
ways to distinguish the positive core.
1. Red sleeve at the end of the cable (prior to cut):
2. Grey text mark every 20 cm through out the cable length:
3. LED left side output:

LED UNITS - CRIMP CONNECTORS
bSeen kits are supplied with loose crimp connectors for the LED units (4 or
5 depending on the kit), plus 2 spare crimp connectors. There’s no need
to strip the wires to connect them. A pair of flat pliers and a small cutters
are the only tools required to connect the wires to the connectors.
On the bottom of each connector, there’s a label to identify the positive
and negative cable’s polarity, as shown below:
Before cutting the cable to size, be sure of the positive polarity, and, if
necessary, mark the cable near the cut spot.

LED UNITS - CABLE CRIMPING
Before cutting the cable to size, be sure of the positive polarity, and, if
necessary, mark the cable near the cutting spot.
To crimp the cable to the connector:
1. Split both cores about 1 inch, and pull apart.
2. Make sure cable’s polarity matches the connector’s polarity, and push
both cores through the guide slots in the connector.
3. With a pair of flat headed pliers, firmly press the connectors’ cap and
crimp the cable.!

ECU - CONNECTORS
On the Basic bSeen kit, the ECU is supplied with four small power cable
tails with mini connectors at the end. The Standard version of bSeen kit is
supplied with five small power cable tails with mini connectors at the end.
Each cable tail is marked with a red sleeve which identifies the positive
core:
Each mini connector it’s identified on the bottom by a label as shown
below:

LED UNITS - CONNECTION TO ECU
After crimping the LED units’ cables to the connectors, these are now
ready to plug into the ECU’s connectors.
1. Invert one of the connectors:
2. Hold both connectors, and push them against each other until you hear
a “click” sound.
3. The positive polarity of the LED unit connector must match the positive
polarity of the ECU’s connector, and should look like the figure below:
