      Ok, I never had intentions of putting on rear fogs, however after purchasing the european automatic light switch, I got tempted because it has the rear fogs option on the switch.

      I wanted to get the euro rear lights with rear fogs, however they only have these in candy red and not smoked lens like the OEM GLI rear lights. Therefor I made my own retrofit. Please be advised that I am not liable for anything going wrong with this DIY. I WILL NOT BE RESPONSIBLE.

      At this point, for those trying to do this mod, I am assuming that you know how to pull wires from the front of the car to the trunk. Also, there are DIY on how to wire the fogs and vag com your vehicle, however I did not approach the vag com. Also I am assuming that you have the European auto light switch with rear fog and the yellow fix cable (harness) that you can buy at vw dealer.

      First you will need to purchase the following:

      *Cree 5w LED or stronger.



      I purchased mine here:

      http://www.amazon.com/gp/product/B008D6RAGU/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1

      *4 rubber grommets:



      went to local hardware store and they had these that worked well. You could get the high temp rubber grommets or regular.



      get 2x 1-3/8"
      get 2x 1-1/8"

      - Get 1.5" hole saw. Got mine at home depot

      http://www.homedepot.com/p/Milwaukee-1-1-2-in-Bi-Metal-Hole-Saw-49-56-9617/202327748

      - 2x 1156 socket got at pepboys.



      - High temp silicone sealant.

      _________________________________________________________________________________

      Lets get started.

      To get the rear fog wiring to work you got two options. 1 is to tap into the bcm, vag com the car and get your rear fogs to work however I found that doing this method will most likely give you a head ache with the bulb out warning unless you put some resistors or canbus error free bulbs. Instead of doing this, I just went with my own relay wiring.



      Euro auto switch pin 7 will be the trigger switch that activates the relay and power on the LED's direct from battery.


      Euro auto switch needs the patch cable from pin 7 to black pin 17 on bcm. (this will enable the dash light to turn on when you turn on rear fogs.)




      Next, take off the rear tail lights. you will need to use the 1.5" hole saw and drill a hole inside the light housing. *** note: please be careful to not push the drill in and scratch/drill inside the lens! I didn't put too much pressure on the drill and let it cut open a hole. I didn't measure or mark where to drill the hole since the 1.5" drill fits right where I wanted it. MAKE SURE YOU VACUUM OUT ALL THE PLASTIC SHAVINGS!!!



      (please ignore that small square next to the round hole... It was a mistake from my initial plan.)

      Now use the big 1-3/8" grommet and put it inside the hole you just made.



      Use the smaller diameter grommet on the bulb itself but you need to cut off one of the lips of the grommet on the bulb so that it would fit easier inside the housing.




      Use the high temp silicone sealant as a lube on the small grommet mounted on the bulb and press it onto the big grommet that is inside the housing.



      At this point it should sit pretty tight and flush inside the light housing.

      NOW onto the wiring. from the relay you will have the 12v wire going to the trunk and onto the factory harness. use the pin #4.




      On the factory bulb socket, wire the aftermarket socket on as so:



      The black wire is positive and the silver wire is negative.


      Now that everything is ready, gently connect the socket to the led bulb and assemble back the housing with the bulb carrier plate.




      Put back everything on as it was before and the final results should look like this:





      Now mounted on the car and working:






      The lights are bright to the point that it bugs people behind, gets their attention but it doesn't blind their eyes too much.



      Cheers! hopefully someone will like this mod... I did...
