This Audi A4 B6 retrofit kit contains everything you need to convert your halogen setup into powerful bi-xenon projector headlights. Featuring custom-made mounting brackets, all the correct wiring and a selection of OEM-style shrouds, it makes retrofitting quick and easy. And, most importantly, it will take your A4 to the next level – just check out the test pictures! This is way beyond what the majority of OEM projectors can achieve.

Of course, with the Mini H1 being such a common retrofit, there are plenty of cheap kits on the market, many of which are claiming superiority by labelling themselves version 6.0, 7.0, etc. But names are pointless here; what matters is the actual output, so we’ll let the test pictures speak for themselves.

You get what you pay for.

Retrofitlab’s Mini H1 series are without question the most popular bi-xenon designs in our range, and for good reason. These are in fact the very brightest projectors available for direct mounting in H4 and H7 reflectors!The Mini H1 Primo is our original design. It provides a dazzling light output unmatched by most OEM projectors. Yet, this is the more basic of the two models.

The Ultimo is our new Mini H1 design. Going beyond even the Mini H1 Primo, it offers a further 20-25% improvement in light output! In addition to its superior reflector, the Ultimo also features improvements such as a rock-solid threaded bulb mount and an alloy steel lock nut.

For a side-by-side comparison of the Mini H1 Primo and the Mini H1 Ultimo, check out this video. You can select the Ultimo or the Primo in the options menu above. No matter which model you pick, you will enjoy crystal-clear 2.5 lenses, colour temperatures ranging from 3,000K to 6,000K and a wide low beam with a bright hotspot and sharp cutoff. The high beams are like the sun – truly impressive for a projector this compact.

Such a light output would not be possible without efficient ballasts, and the included Aharon digital ballast has – as opposed to many other aftermarket units – been tested to generate a full 35W. The Aharon comes in a rugged and extremely compact housing perfect for retrofitting, and its in-wire starter warms xenon bulbs in as little as five seconds. It is also Canbus-proof, so you won’t get any bulb failure readings on your display. This ballast is the perfect complement to the included Audi A4 B6 wire harness, which connects directly to the original wiring. A high beam splitter is also included, making for easy integration of the bi-xenon mechanism. Power supply is strong, steady and reliable.

The Aharon ballast ensures that you get maximum possible light output. However, any ballast with AMP connectors is technically compatible with this kit.

This complete Audi A4 B6 retrofit kit is inspected by our internal quality control prior to shipping and comes with a solid 2-year warranty. It also includes highly rated technical support from your lighting experts at

We look forward to brightening your day (not to mention your night)!

This is an easy retrofit that even complete novices can do, but those with more skills and experience will be quicker. Discounting removal and replacement of the headlights, you could expect the job to take anything from less than one to two hours.

You do not even have to open the Audi A4 B6 headlight. Simply remove the existing projector through the bulb access port at the rear and replace it with your upgraded projector. Done.

This complete kit has been especially developed to enable retrofitting at home, saving you the cost of installation.

Good kit, but the instructions could be a bit better. Like a piece of paper with a few pictures would have been enough.

I had halogen headlights in my Audi and I wanted better so this was obvious choice and I just can't be more happy about this set.

Excellent light output for the b6 better than original headlight and easy to install
Is the best solution for your audi a4 b6

Hight quality products, easy to install and worth the price!

Good service and very fast delivery the Kit works great easy to install and those Youtube videos are great!
Thank you Retrofitlab!

MH1 with XB35. Easy installation. Maximum satisfaction with light output. Previously had halogen projectors with OSRAM night breaker h7 bulbs but compared to MH1 is like I was driving with candles!!! Thank you Retrofitlab.

Installation was easy and your video was also helpful. Lights are now far more better than OEM halogen bulbs with worn out projectors and i think these aren even better than bi xenons in my MK5 golf.

De set wordt geleverd als een universele set uitgebreid met 2 montageringen die de set passend maken voor de koplampen. De montagegaten op deze ringen zijn erg krap, en kunnen naar mijn inzicht wel 1mm groter in doorsnede voor meer montagegemak. De elektronica komt als ik kijk naar de stekkers uit China, vrij grove stekkers die moeilijk netjes weg te werken zijn. Na alles te hebben aangesloten had ik een mooi lichtbeeld en werkte het prima. Vergeet niet de aarding goed aan te sluiten, ik merkte al dat mijn radio stoorde als dit niet goed is gedaan.
