This Audi A6 C4 retrofit kit contains everything you need to convert your halogen projector setup into powerful bi-xenon HID 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 Ur S4 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 labeling 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 4300K to 6500K 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. Also the original leveling system keeps working.
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 A6 C4 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 kit. Lastly, this kit provides every single part that you will need for retrofitting. For absolute top performance, we advise that you upgrade to the premium Aharon XB-35 5500K bulb instead of the regular H1 bulbs. This powerful bulb represents excellent value for money, featuring an extremely high light output in a modern white colour.
This complete Audi A6 C4 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 Retrofitlab.com

Installation
This is a fairly straightforward 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 one to three hours.
Simply open the Audi A6 C4 headlights (they’re sealed with butyl, so that’s a quick job), mount the projectors and shrouds, and reseal. Done.
