DIY: Installing auxillarylights on Halogen or Bixenon Golf Mk7

I just did this on our Golf Mk7 GT and the difference in light throw on highbeam is amazing. The basics are the same, but you might want to choose a diffent lamp then I did. This DIY will let you hook the lights up to operate with the stock highbeam. I´ll assume that you know how to remove your grill for access, its just two torxs screws and abit of pulling.

There are hundreds of different models and applications, but I can show some examples below. Helped me decide on lights anyway
I used an auxillary light holder bought from a local company to mount the lights. Simply a 7mm steel plate with "ears" in which to mount the lights. Ridgid industries and several others offer variants of this mount. You will ofcourse need to remove the fron licenseplate and holder (If applicable)
Rigid industries make one http://www.rigidindustries.com/mounting-options/40016



The plastic in the bumper is quite thin, so I mounted some large washers and used 6mm screws with a locking nut on the inside. Its abit tricky to mount, but it can be done without removing anything.


Once the plate is in, you will need to do the electrical wiring. This isnt hard, you just need to follow the instructions on the relay harness. We bought a solid state closing relay used for cars with "sensitive electronics" from SEPAB in Sweden.

You need to run 4 leads and mount the relay
First we found a mounting point that could also act as a ground. Thats ONE wire done.


1. Permanent plus (or power from the battery) (two leads). I ran these inside the existing leads/wire channel on the firewall


2. Get the "Signal to light" from the existing harness on the golf.
For Bi-xenon cars, this is PIN 11 on the contact to the headlight. That contact comes out by depressing the locking tabv and pulling straight out


On HALOGEN cars, its PIN 8 - White/Purple


Then mount the relay and hook the ground wires (Two leads) up under the bolt.


The only thing remaining is to run the two wires containing both ground and power from the relay to the lamps. I didnt get any shots of this. But is fairly straightforward. Then connect the leads to the lights as the manufacturers instructions explain.

Some exampals of lights fitted to the Golf MK7.
LED ramp


2x VisionX LC25W fitted on either side of the radar


2x Hella FF200 fitted on a "numberplate mount"


2x Hella 3003 Compact fitted as the DIY


3x 225mm SIM lights fitted to numberplate mount


3x NBB 175 on numberplatemount

I´ll end with a last one.

This is the diffrence you get with just 2 good auxillary highbeam lamps using Xenon technology. In this case on a MK6 GTi
The diffrence in width and lenght of the highbeam is hugely increased, allowing the driver to spot wildlife, debris and such sooner and also allowing more safety and a more relaxed drive during the darkest season.

First is lowbeam (Halvljus)
Second is stock highbeam (helljus)
Third is stock highbeam plus two Hella Luminator Xenon highbeams (Helljus plus 2xenon).

Dont Normally bumb my own thread, but found this in a local paper. The guy has installed a LED lightbear in his front grill!!

Surely this impacts the airflow? (with regards to the Light bar addition...)

Probably, but not greatly in that Golf. The TGi and GTI have the same cooler, but the TGi engine generates less heat.
Besides, it rarely goes above 25C here in Sweden.
