Bi-Xenon retrofit question

I have a 2001 330ci coupe.

I have the opportunity to buy some OEM bi-xenon projectors for a good price. I can either get the OEM ballasts (with wiring for bi-xenons) or Hella ballasts (with wiring just for one bulb) with the projectors. How difficult would it be to retrofit these given that 2001s didn't come with bi-xenons, only xenons.

Also, would the type of corners be different as well?

If you are retrofitting these into your current headlight housing, it'll use the same style corner that you currently use. Retrofitting is relatively simple if you know what you're doing.

I'm getting the complete projector so I wanted to swap out the whole thing?

Also, I don't really care about having xenon hi-beams I just want lo-beams and would be okay with halogen hi-beams.... what is the easiest way to achieve this given my options above?

Oh, if it's the complete assembly (headlamp and all), it's just a matter of taking out the old ond and putting in the new one if its from a prefacelift coupe. Bi-xenon units use screw-in corners though, so you'll have some options:

#1 - Buy screw-in corners (easiest route, but costs more) to replace your clip-in and sell yoru clip-in in classifieds

#2 - transplant all bi-xenon internals into your current clip-in headlamp housing (timely, but least costly since no extra parts are required if you have basic tools) so you won't have to buy screw-in corners.

Ok that sounds good. So now for the headlights themselves. Which ballast would be better/easiest to go with? What kind of wiring is going to be involved? Am I going to get headlight out warning messages? I'm pretty much resigning the bi-xenon capability because from what I read it's very difficult to do on a 2001 car...

There are a really only two things to question yourself on:

Which is more important, the functioning of your flashers, or HID high beams (mind you HID high beams are unbelievable once you've had them, you won't want halogen high's)?

And how good are you with wiring?

The bixenon's aren't impossible to retrofit by any means, E36 guys do it so I know you won't have too much of a pain. The only thing I remember being a question was the input voltage for the cutoff switch (bixenon feature) and you may need to put a resistor in, but a bunch of guys ran the 12V with no trouble as well.

If you are going the OEM route, at least get the bixenons. That way you can justify spending $600 on a used set of headlights by the fact that you have xenon high beams.

With that said, standard xenons are in no way horrible in comparison. If you are going with the standard xenons, I highly recommend you take a look at our Projector46's which are BRAND NEW headlights for the same price as a set of used OEMs. These come with a full lifetime warranty, plug and play installation, email/phone/AIM support and an installation guide for your convenience.

Feel free to contact us with any questions
