BMW 3 E46 98-05 bi-xenon headlight repair & upgrade kit for bi-xenon HID headlights made by ZKW

This BMW 3 E46 ZKW retrofit kit contains everything you need to swap your old, blacked-out single-xenon (low-beam xenon only) projectors for powerful new bi-xenon (both low- and high-beam xenon) projectors. Using the exact same mounting points it makes retrofitting quick and easy. And, most importantly, it will take your 3 series E46 to the next level – just check out the test pictures! This is way beyond what the majority of OEM projectors can achieve.

The Mini D1S\D2S is an incredibly bright bi-xenon projector, enabling you to keep using D2S bulbs, including the most powerful options from Osram and Philips. Available bulb colour temperatures range from 4300K to 6500K. You will literally outshine the competition. The crystal-clear 3.0-inch lens throws a wide low beam with a bright hotspot and sharp cutoff. As for the high beam? It’s like the sun. And because only the projector is replaced, the leveling system keeps working as original.

Such a light output would not be possible without efficient ballasts. If you’re happy with the ballasts that you’ve already got, simply leave them in place. Alternatively, add a set of our Aharon digital 35W ballasts to your order. The Aharon ballast has – as opposed to many other aftermarket units – been tested to generate a full 35W. It comes in a rugged and extremely compact housing perfect for retrofitting, and its in-wire starter warms xenon HID bulbs in as little as five seconds. The Aharon ballast is also Canbus-proof, so you won’t get any bulb failure readings on your display. Please be advised, the input is a 9006 type connector, OEM ballasts usually have different input connectors. So you will need to find the Positive and Negative wire which are used for the low beam signal to connect to the input of the ballast. Also mounting will be different. So this requires some DIY. A high beam splitter is also included, making for easy integration of the bi-xenon mechanism. With the Aharon ballasts and wiring, power supply is strong, steady and reliable.

Lastly, this kit provides every single part that you will need for retrofitting. In order to keep the price low, we have however assumed that you will keep your existing xenon HID bulbs. Depending on how old those are, you may want to also order a new set of bulbs to get the most out of your retrofitted system. Xenon bulbs do lose up to 70% of their maximum brightness over time.

This complete BMW 3 E46 ZKW etrofit 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

Should you have any questions prior to purchase, please refer to our FAQ page or start a chat below. You can also download our free brightpaper on automotive lighting. Nothing beats making an educated decision!

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

Installation
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 have to open the headlights, but with the E46 headlights, that's only a matter of opening the clips. and replace it with your upgraded projector. Done.

When you fit new headlight lenses, you can’t just reuse that crusty old rubber seal—swap it out for butyl. Here’s why:

  1. Compensates for imperfect fit
    Aftermarket or reproduction lenses almost never match OEM tolerances exactly. Butyl fills in any tiny gaps or misalignments, ensuring a snug seal even if the new lens isn’t a perfect fit in the housing.

  2. Longer lifespan
    Butyl won’t dry out or become brittle in extreme temperatures. It’ll keep its seal through heat, cold and everything in between—so you’re not chasing leaks every year.

  3. Easy to apply
    Just heat it up a bit, stretch it out, press it into the groove where the lens sits, install your new lens, and you’re done. No messy solvents, no worries about gaps.

Bottom line: new lenses don’t sit 100% snug, and old rubber seals lose their mojo over time. Replacing that crusty gasket with fresh butyl when you install new headlight lenses is the simplest way to keep them clear, dry and firmly in place.
