Step 1: Mounting & Wiring The Billie Brake Light
Congratulations on the purchase of this revolutionary Billie brake
light. This is a high output brake-tail light that is computer controlled by the
Clearwater CANopener. This brake light is intended for use on specic BMW
motorcycles that use the CANbus control system.
This brake light installs in place of your license plate frame (our apologies to your
dealer for robbing his valuable advertising space). The Billie brake light and frame
are CNC machined from billet aluminum and are very solid. The aluminum frame
not only helps mount your license plate, but also serves as a heat sink for the
powerful RED LED emitters.
Installation is simple. Just feed the small black cable up through your bike’s rear
fender section and up to the area under your rear seat. Then, secure your license
plate to the Billie frame with the included bolts. Use the included bolt spacers if
there is any chance for the grommet to become kinked against the rear fender.
Now, connect the RED wire from the Billie to the RED wire coming out the back
of the CANopener. Finally, connect the BLACK wire from the Billie to the BLACK
wire coming out of the back of the CANopener. Ignore the yellow wire on a BMW
installation.
Check routing of wires and tuck the CANopener back in place.
Note: The bike must be running for the brake light to function.

How To Adjust Brake Light Intensity:
1. To enter the dimmer program, you must rst hold the front brake lever. Next,
press and release the Turn Signal Cancel (TSC) switch once before holding the WW
to the right for (2) seconds. The light will ash twice, indicating you’ve entered the
dimming mode. The brightness on the brake is adjusted by continuing to hold
down the front brake lever while rotating the WW. The brightness on the tail light
is adjusted by releasing the front brake lever before rotating the WW.
2. Wait 3 seconds with no adjustments or press the TSC again to end the program-
ming mode. A single ash indicates end of programming mode.
Note: There are two settings for brake and running light levels: day and night. The
ambient light sensor in the instrument cluster determines the level the light is set
to during night or day. The daytime levels can be adjusted by shining a ashlight
at the instrument cluster. Conversely, the instrument cluster can be covered up to
adjust the nighttime levels.
How To Adjust Brake Light Modes:
While stationary, press and release the TSC, then press and release the front brake
lever 5 times within 5 seconds to cycle through Modes 1 - 4. When cycling to a
new mode, the brake light will ash a number of times equal to the mode it is
now in.
Mode 1 – No brake light.
Mode 2 – Standard brake light; functions identically to BMW brake light
(default on Version 1.7 and later).
Mode 3 – California compliant brake mode; 4 ashes at 4 ashes/second when
front/rear brakes applied followed by constant on. Disabled below 5mph.
Mode4 – Active brake light; ash rate depends on deceleration rate. Disabled
below 5mph.
Stationary Brake Flash (CANopener Version 1.82+):
The brake will not ash in modes 3 or 4 if the speed of the bike drops below
5mph. This is to avoid the nuisance of ashing in heavy, stop-and-go trac.
If ashing is still needed while the bike is stationary, a 4-ash burst can be
generated by pulling on the brake lever twice. If the user is holding onto the
front brake lever, releasing and holding the brake lever again will activate 4
ashes.

Automatic Brightness (CANopener Version 1.82+):
In Brake Modes 3 and 4 (the two brake ashing modes), the brightness
of the brake light is automatically controlled by the rate of deceleration. Light
braking always results in a minimum of 25% of the dierence between the
brake and tail brightness levels. This will increase to the full programmed brake
brightness at a deceleration rate of 0.4G is reached.
For very vigorous braking, the intensity can even exceed the
maximum programmed value (see previous programming discussion) for
braking above 0.4G, limited only by the maximum brightness of the brake
light. As the bike comes to a stop (below a speed of 5mph), the brake light
returns to the programmed braking brightness as long as the brake lever
(or pedal) is held.
For example, if the tail level is set to 20%, and the brake level is set to 60%, the
dierence between the two levels is 40. 25% of 40 is 10, so at bare minium, the
brake light brightness will increase to 10% above the tail light level, i.e 30%.
As the deceleration increases, however, the brake light will increase,
reaching the full programmed brightness of 60% at 0.4G of braking.
However, under very heavy braking in an emergency situation, the brake
can reach the full 100% brightness that it is capable of at 1.0G (highest
typical braking rate based on tire traction), regardless of the maximum
programmed level.
Inertial Braking (CANopener Version 1.82+):
When the CANopener is switched to California legal strobe mode (mode
3) or speed sensitive mode (mode 4), the brake light automatically engages
when the deceleration of the bike reaches a threshold value, even when the
brakes are not engaged (engine braking).
Once the CANopener is in mode 3 or 4, there are 3 subcategory modes
that can additionally be changed (see chart on Pg. 8). To switch between these
modes, while stationary, press and release the TSC button, then press and
release the rear foot brake lever 5 consecutive times (front brake released). Each
mode will be signaled by a corresponding number of ashes by the brake light
as well as by any other clearwater lights you may have installed.
- Inertial Brake Mode 1a: Inertial braking disabled. The front and/or back brake
lever must be engaged for the brake light to activate.
-Inertial Brake Mode 2a: Low sensitivity mode. The brake light will activate when
the engine braking level reaches 0.4G.

Inertial Braking Mode (CANopener Version 1.82+):
-Inertial Brake Mode 3a (Default Mode): High sensitivity mode. The brake light
will activate when the engine braking level reaches 0.2G. This will make the
activation of the brake light during engine braking happen more frequently,
under less deceleration.
Inertial braking is disabled during standard brake light mode (Brake Mode 2)
but works equally well using the California 4-ash (Brake Mode 3) or variable
ashing (Brake Mode 4) modes. In either of these modes, the brake light will
appear just as if the rider had engaged the brake, including the programmed
ashing and automatic brightness control.
Adding mechanical braking at some point during the engine braking
process provides seamless, uninterrupted action of the brake light.
Factory Reset Default:
To reset the CANopener to the factory settings, press and release the
TSC button, hold the turn signal to the left, then press and release the ash-
to-pass button 6 times within 6 seconds. Release left turn signal. All factory
preset dimmer levels and modes will be selected.
A successful reset is indicated by ve ashes of the Clearwater lights.
Billie Indicator Light:
Included with the Billie Brake Light Kit is an optional feature that
allows the user to conveniently monitor what the Billie Brake Light is doing
while on the bike. The Indicator light is very simple to install. Fasten the LED
to an area that can be easily seen when riding, then route wiring to the
back of the bike near the CANopener. Next, the red and black wires from the
Indicator light will be Posi-Locked to the CANopener red and black wires,
along with the red and black wires from the Billie Brake Light. The image
below shows our recommended mounting location.
