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.
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
hazard warning lights, horn and headlight control.
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.!

INSTALLATION
bSeen Xiaomi edition was designed to be installed inside your Xiaomi’s
deck, and it uses Xiaomi’s battery power to operate.
INSTALLATION - HANDLEBAR CONTROL UNIT
With the electric scooter upright, start by removing the handlebar grip by
sliding it, as shown below:
PROCEED WITH CAUTION AND READ CAREFULLY
The installation of the bSeen kit requires basic electric skills, such as
connector block connections and stripping electrical wires.
If you’re not familiar with such proceedings, ask for support from your
electric scooter dealer or from an automotive electrician professional.
Damage to the bSeen ECU, LED units and/or Handlebar Control Unit
due to faulty connections, short circuits or polarity inversions, will not be
covered by warranty.
Step 1
Step 2

Once the handlebar grip is removed, install the bSeen Handlebar Control
Unit in place, and tighten the hexagonal screw located at the back of the
unit.
Cut the handlebar grip to size and re-fit it.
Tighten the hexagonal screw located on the back, to
securely hold the Handlebar Control Unit.

Step 4
Step 5

The Handlebar Control Unit is supplied with a 2 metres cable length and a
Higo connector. The cable runs inside your Xiaomi’s stem, along with the
brake line - usually a red cable.
Insert cable inside the stem with the
brake line
With the help of a pair of pliers, grab
the cable at the bottom of the stem
Leave the cable loose until you got the
battery compartment opened.

INSTALLATION - REAR LED UNITS CABLES’ PLACEMENT
Start by securing your Xiaomi on the top of a solid surface or support.
Usually a table top, a work bench or a keyboard stand are the most
common supports used to work on electric scooters.

Remove the rear wheel plastic covers, remove the rear wheel and open the
battery compartment.
On both rear wheel plastic covers, drill a small hole and snap one of the
plastic guide pins inside, as shown below.
Drill a hole large enough for the LED
unit cable
Snap one of the plastic guide pins
inside the wheel cover
ATTENTION
The hole drilled needs to face the front of the scooter

Choose one of the rear LED units and start running its cable through the
hole on the scooter’s frame. Make sure the hole is the one which
corresponds to the guide you snapped on the previous step.
Repeat the previous steps for the opposite LED unit - on the opposite fork.
Run the cable length through the frame’s hole
Use the small cavity on the frame to run the
cable through, and then pull the cable
through the bottom of the fork.
ATTENTION
Do not run the whole length of the LED cable. On the LED side, leave
slack enough to allow the LED unit to be mounted on the wheel cover.

Unplug the tail light connector and remove the rubber grommet. This will
allow both LED cables to go inside the battery’s compartment.
Run both cables on the gap between the battery pack and the scooter’s
frame, and leave them loose where the ECU unit will be mounted (see
page 6).
The original rubber grommet won’t house the extra cables. By the end of
the installation, in order to seal the hole against water and dust, we
recommend the use of silicone. !

INSTALLATION - FRONT LED UNITS CABLE PLACEMENT
The front LED units are mounted on the plastic covers - as shown on the
picture below.
The left LED unit cable runs through the head tube along with the brake
line and the handlebar switch cable - left loose previously.
The right LED unit cable also runs through the head tube along with the
motor cable (grey) on the right side of the electric scooter.
Run Handlebar Control Unit’s
cable - left loose previously.
Run LED Unit’s
cable along with
the brake line and
the Handlebar
Control Unit’s
cable.
Fit the LED unit
onto to the plastic
wheel cover.

INSTALLATION - CONNECTIONS OVERLOOK
Once all cables are in place, these need to be connected to the ECU.
The Handlebar Control Unit cable has a fixed Higo connector at the end,
and the connection is made directly onto the ECU.
The LED units’ cables are supplied with extra length, and these, if you wish,
can be cut to size.
Each LED unit cable is marked with a red sleeve, which indicates the LED’s
positive polarity.
!
ATTENTION
If you wish to cut any LED cable to size, make sure you mark the positive
polarity prior to the cut.
Inverting polarities won’t damage neither the LED unit, nor the ECU unit.
The result will be a non blinking LED unit, and the connection to the
ECU will need to be re-done.

The ECU for the Xiaomi was designed to fit in the gap between the
Xiaomi’s controller and the head tube, inside the deck.
The ECU has connection points on three sides of its enclosure:
To avoid possible damage to the cables from the battery cover, the LED
unit’s connections are made on the bottom of the ECU, as shown bellow:

We recommend to simulate your ECU’s final placement prior to the
connections. This will help you to understand how to manage your cable
cuts and cables’ final placement.
The ECU slides in an angle until it sits inside the scooter’s frame:
Tidy up all cables surrounding the ECU’s location, such as the grey cables
and the red brake line cable, and insert the ECU as shown bellow:

INSTALLATION - CONNECTIONS - LED UNITS
The LED units connections are made on the left connector block (view
from top of ECU). The Right LED units - front and rear - are connected in
parallel mode. The same applies for the Left LED units - front and rear.
You will need to strip the wires in order to connect them to the ECU’s
connector block.
With a small cutter or a Stanley knife strip each core about 1 inch (2.5cm):
Join the positive cores and the negative cores of the Left LED units (front
and rear), and do the same for the the Right LED units (front and rear):

With the cables joined as shown above, insert them in the connector block
and tight the top screws to secure each connection:

Right indicators
ATTENTION
Double check the cables’ polarities, and make sure there are no wires
touching each other between the connector blocks.

INSTALLATION - CONNECTIONS - HANDLEBAR CONTROL UNIT
The connection to the Handlebar Control Unit is made via a 6 pin
connector.
Inspect the interior of the connectors before plug them in. The pins inside
the male connector are fragile and can bend if both connectors are offset.
There’s also an arrow icon on each connector’s enclosure. Aligning both
arrows will ensure you the connection can be made.
Once both arrows are aligned, apply some pressure to secure the
connection.
You might be left with some extra handlebar control cable. This leftover
can be coiled inside the head tube, underneath the ECU.
