Check with local authorities before operating
a motorcycle with auxiliary lighting systems.
Laws vary state to state, and what may be
legal in our jurisdiction may get you a ticket in
another jurisdiction. Usually during daylight
hours the authorities turn a blind eye toward
the operation of auxiliary lights, but your
mileage may vary.
For safety reasons, make sure that auxiliary
lights do not interfere with or block a
motorist’s view of your signals.
When bright auxiliary driving lights are
activated it may be difficult for other drivers to
see the front turn signal as it flashes.

Wiring Auxiliary
Light Systems on a GS
The following information was taken from the
instructions we prepared for the standard
1200GS. The same basic principles apply to
the Adventure.
BestRest provides the following information
as a courtesy, free of charge. This
information relates to our personal
experiences involving installation of auxiliary
lighting systems on our personal motorcycle.
Read and follow the installation instructions
and wiring diagrams that came with your
lighting system. If you're not sure how to wire
the lights contact the manufacturer or seek
professional installation assistance. If you
don't understand 12 volt wiring systems, can't
operate a voltmeter or ohmmeter, or if you
can’t crimp or solder wire connectors, then
you shouldn’t attempt the installation.
Note: The R1200GS has a very sophisticated
computer controlled electrical system. If
you're not careful you could damage the
entire computerized ignition system, resulting
in expensive repairs and replacements. For
this reason we recommend all accessory
wiring be done directly from the battery
terminals, independent of the BMW wiring
harness.
Battery: Before you begin any work
disconnect the battery. Reconnect when
your work is complete.
Fuse: For safety reasons we recommend
that any auxiliary lighting system be
connected thru a fuse. This is necessary in
the event of a short circuit.
Relay: We recommend using a relay. A
relay is designed to handle and control the
large amperage (current) draw needed by
auxiliary lighting systems, without causing
damage to your electrical system or switches.
An exception to this rule is to establish a low-
amp 12V relay command circuit that’ll be
used to turn on/off the high-amp lighting
circuit within the relay. We tapped into the
positive (+) wire that runs from the BMW
accessory outlet. Because the current drain
for the relay is low, the computer thinks it’s
just another accessory gadget plugged into
the outlet. An added bonus of using this
technique is that the outlet is on a timer.
About 30 seconds after you turn off the
ignition, the outlet is deactivated and your
auxiliary lights will shut down, if you haven’t
already turned them off.
Gas Tank: You should remove the gas tank
and other body panels in order to wire the
lights. Refer to the attached sheet for helpful
information on that process. Although you
can route the wires without removing the
tank, it makes the process much harder and
give a less professional result. Once the
body panels and tank are removed you can
mount your relay and route your wires.
Piaa Lights
:
For Piaa lights we mounted
the relay below the VIN plate. We Velcro’d
and zip-tied the relay in place.
We routed the wires to a Centec fuse panel
mounted above the battery, on the back of
the air box.
IPF Lights
: For IPF lights we mounted
the relay on the left side of the steering head.
We prefer the IPF systems because of their
compact relay & high quality wiring harness.
We found the IPF harnesses much easier to
install than other brands.
We used the same screw to connect the 2
grounding wire leads of the wiring harness.
The relay must be mounted with the screw
hole up and the plug facing down.
We used corrugated wiring
looms to keep our wires
neat and orderly. We
planned each wire’s layout.
