BMW R1200GS, /A; R1250GS, /A - P3 Installation

Installing a P3 system on the BMW R1200GS or R1250GS is quick and easy. The following instructions illustrate how this is done.

Start by mounting the LED modules on either side of the license plate using the provided mounting brackets.

The next steps depend on whether you have the:

- 2013+ R1200GS (water cooled); 2019+ R1250GS


- 2005-2012 model

2013+ R1200GS, /A (water cooled); 2019+ R1250GS, /A

On this model, start by removing the seat, then the 8 Torx screws that hold the seat rail in place. Remove the rail, then the two screws under the tail light assembly (see photo). Pull the tail light assembly off. 

Remove the three circular clips that hold the tail light lens in place, and pull the lens to the rear, exposing the tail light connector as shown below.

Connect the controller's black wire to the brown wire in the connector, and the controller's white wire to the grey/black/yellow dots wire in the connector. DO NOT use the tail light wire (grey/red) as it cannot support even the small additional electrical load of the P3 LEDs. See below for connecting the controller's red wire.

Locate the small fuse block in directly under the rider seat on right side.


Connect the controller's red wire to the red wire with a blue trace (red with brown trace on pre-2016 models) coming from the 7.5 amp fuse in the fuse block. This is a thicker gauge wire and some customers have used a larger Posi-Tap or other connector.

Note: This power source will stay on for about a minute after you turn off the ignition. The low current draw of the P3 system will not drain the battery by any appreciable amount  during this time. Our Photon Blaster front visibility lights can also be powered by this source.

If you are installing the P3-TS model, connect the controller's yellow and green wires  to the, right and left respectively, blue turn signal wires shown in this photo:

Once completed the overall wiring will then look like the photo on the right.


The last step is to tidy up the wires using zip ties or tape so that the wires do not interfere with the seat rail or seat.

Programming on the R1200GS-W (2013 and onward models)

Note:  The brake light on BMW's water cooled R1200GS stays on for a minimum ~ 1/2 second after you release the brake lever or pedal, even if you tap the brake lever for a shorter period. This requires you to enter the programming pulses more slowly than on other bikes. When you release the brake lever or pedal, you need to watch the brake light to see when it goes out before you can enter another pulse.

The current IQ-260 series controllers (version, v10) have a programming method that accounts for this delay. but you still need to wait for the brake light to go off before entering another pulse.

On our earlier P3 Lights controller's, up to and including firmware version v9 (marked on control module's label), this brake light peculiarity restricts the number of brake light pulses that can be entered within the 5 second programming window.  Please consult this section for programming details

2005 - 2012 R1200GS, GSA

After mounting the LED modules, remove the three Torx screws under the rear seat seat and lower the tail light assembly down so you can access the wires going to the tail light.


The location of these three screws is marked by the yellow circles in the photo showing the view under the tail section of the R1200GS.

NOTE: On the R1200GSA, you will need to loosen the side bag carrier frame in order to lower the tail light assembly. 

You now can see the tail light assembly (see photo below). To give better access to the tail light wires, wiggle the black zip tie attached to the cable anchor until the anchor pops out of the tail light base (see photo below).


Then attach each of the three gray/red Posi-Tap® connectors onto the Brown (ground), Gray/Red (tail light), and Gray/Black (brake light) wires as shown below.  NOTE:  the photo shows older style T-tap connectors.

Next connect the P3 Lights controller wires as follows:

  • controller's black wire to the tap on the Brown wire

  • controller's red wire to the tap on the Gray/Red wire

  • controller's white wire to the tap on the Gray/Black wire


NOTE: some models with an LED tail lamp have only two wires going to the tail lamp, and two going to a separate license plate lamp. If this is the case with your bike, connect the controller's red wire to the wire going to the license plate lamp, and the white and black wires to the wires going to the tail lamp brake and ground wires, respectively.

For model years 2011-2012, you should connect the controller's red wire to the Green/Blue wire in the diagnostic connector, shown in the diagram below the tail light wires photo. This connector is located under the seat. An alternate connection point is the Blue/White wire powering the front parking light. This wire is in the headlight connector.  

Replace the zip tie attachment in the hole.


  • Route the wires from the LED modules up through the vertical channels behind the license plate.

  • Connect the copper wires to the ground and the silver wires to the controller's gray/green wire as described in the standard installation instructions

  • Secure the controller to the vertical aluminum bracket using the included velcro squares, photo below.

  • Bend the aluminum LED module brackets so that the LEDs are pointing straight back to provide maximum visibility  

You're done! Enjoy the lights, and the added safety.!
