P46s vs. OEM Bi-Xenons

I'm kinda new to the whole lighting thing... someone help me out. Price not being an option, what are the benefits of going with one or the other?

In all honesty there's no point in spending the money for OEM Bi-Xenons... not only will the Bi-Xenon feature never work with your car (You don't have the proper LCM and to buy a new one is expensive), but the OEM Auto-Leveling won't work because you don't have the sensors on your control arm (You'd need to buy a new control arm with a place for the sensor to go!)

P46's don't have those features, but they work perfectly with your car's setup, they come with angel eyes, they're available with different color HIDs, and they are less expensive!

Call or Email with any questions!

Also, on Umnitza, it says:

E46 2 door Euro headlight assemblies complete. Headlights have H7 low and high beam capability, daytime running light capable, are PnP***8482; (plug and play). No need to have your dealer reset to eliminate error on dash unlike the OEM alternative.

THESE DO NOT INCLUDE HID

What does it mean by "These do not include HID"?

What's the difference between Xenon and HID? I guess I'm a bit confused.

HID is the same as Xenon. Umnitza's site is confusing you. Please read ours for a clear description.

With all due respect, as I know you are a site sponsor, some of the above is not factual. He has an 03 which will support bixenon operation just fine with a little bit of wiring and a quick visit to the dealership for retrofit coding.

The front/rear right side control arms are all predrilled and the sensors/brackets are relatively cheap, although you are correct that the LCM will not support autoleveling and that is expensive and a dealership hassle to replace/reprogram (the mileage is replicated there). The wiring harness is a PITA as well.

I've helped over 100 people convert to OEM bixenon. It isn't that hard.

As I said, I dont mean to knock anyone's product, I only want to represent the facts.

Thanks for the info, I was unaware about the control arms being pre-drilled. Nonetheless we feel our product is a more viable option as it offers more usable features for less money! A new LCM is a big added cost to get the full functionality out of the OEM xenons.

Thanks again for your input

he doesnt need a new LCM tho, he just needs a reflash at the dealer, i got my friends LCM reflashed for Bi-xenons for free, wired it up to bi-xenons in about an hour, now hes got full functionality, full cost=less than $500

Yeah, I was really going back and forth after we PMd the other night. The best I could find was about $650 shipped. Then I realized that by the time I added in an angel eye kit, I'd be over the cost of the P46s. Maybe some day I can pick up a set of OEMs so I can get the bi-xenons. I think I'll be happy with these right now, though.

What is the exact definition of bi-xenons and how do they differ from regular xenons?

Bixenons utilize a flapped based low beam headlight that functions as both your high and lows. Regular xenons use the outer low beam xenons as your low beams and the inner halogens as your high beams. On bixenons, the inner halogens only function for DRLs or flashing your high beams.
