Hi All,

I recently bought a 2012 BMW R 1200 R Classic. I love it. I want to install some Motolights so I got everything bolted on and then went in search of a switched power source lead to TAP into as per the instructions for installation of these auxilliary lights. The headlight on the 2012 has one plug going into the rear of the headlight housing and this plug has all the leads for the Parking, low beam and high beam bulbs. I would like to know which lead is for the Parking light or even for the low beam as I would like to TAP into it for the motolights. Trouble is I can't figure it out and there's no Haynes manual for this bike yet. Anyone know? I see four colored leads:-

  1. brown - which I believe is Ground
  2. Yellow - dunno
  3. White - dunno
  4. Blue and White, I think - dunno

Can anyone tell me which of the three dunnos is the parking light? Really appreciate it

Thanks in advance,

R

I have the BMW service manual; but, I am out of town until tomorrow. If no one responds sooner, I will look it up for you when I get home.

I installed some extra lights last year, if my memory doesn't fail me, I think the parking light is the blue and white wire.

Checked the service cd. It is not helpful; however, I recently installed additional lights and successfully tapped into the yellow and white wires at the headlight plug to power them when the low beam is on. Hope this helps

Thanks las and Hoshiko, I now have two options to try..one of them and likely both of them will work.

How I found the Switched Power Source

Just to bring this issue to a close and perhaps help someone else with a similar quandary, I ended up using a multimeter to determine that the parking light on my 2012 R1200R Classic is the blue and white lead entering the headlamp plug. How?

  • Turn on Parking light only
  • Remove headlamp and disconnect the singular plug (with 4 colored leads)on back
  • Set meter to measure DC volts
  • Ground to engine frame
  • Probe each of the cable electrodes, the one registering a voltage is the parking light.
  • Disconnect battery, install motolights and switch

You can get a multimeter from your local electrical store or one of those warehouse like home supply places for about $22 - if you cannot borrow one from a friend/neighbor.

Finished installing my moto lights. Man they are bright!!! I'm like the sun driving along the road. I bought the LED bulbs.

Hope this might help others and thanks to all who chimed in and tried to help me.

Thanks for the info, some pictures would make it easier for mechanical challenged people like me.

Great but I'm sure the :mob: agrees that One Picture is Worth a Thousand Words

Hoshiko, I don't have photos of me driving along the street on the bike at night with lights ablaze but I'm happy to answer some Q's you might have...where my explanation failed you in some way? Where did I lose you technically?

Was trying to figure out which one is the high beam for a set of Clearwaters.. at least you gave me 50/50 odds now if I can remove brown and blue/white.

Thanks!

Hi All,

I had this same predicament when installing my motolights, however used a test light to check which was hot when the ignition and low beam was on. Easy job with a little know how :smile2:

I ran wire through the plastic plug into the rear of head light shell, (where I tapped into the low beam power), to keep everything nice and tidy.

My install was too long ago, I can't recall the colour of wires I'm afraid....
