How do I know if I have factory xenon or factory halogen (non-xenon)?
Go ahead turn on BOTH your low beam and high beam for 30 seconds.  If you see both high and low beam have the same yellowish color after 30 seconds, then you have the halogen model.  If you see low beam is whiter than high beam after 30 seconds, then you have factory xenon model.

 

What is Bi-Xenon?
Definition of Bi-Xenon, Regular Xenon only has Low Beam that operates Xenon.  A Bi-Xenon has BOTH Low and High Beam operate Xenon.  In other word, regular xenon, when you turn on low beam, xenon is on, but when you turn on high beam, it's regular halogen.  For Bi-Xenon on the other hand, when you turn on Low Beam, Xenon is on, and when you switch to high beam, Xenon still operates, but produces further outward beam for high beam projection.

 

What is LHD and RHD?
LHD stands for Left Hand Drive while RHD stands for Right Hand Drive.  LHD is what USA, Canada and majority of European countries use, meaning the driver is on the LEFT side of the car.  While UK, Japan, Hong Kong, Australia.... has the opposite, RHD, meaning the driver is on the RIGHT side of the car.  Due to the road is on the opposite side between the 2 systems.  Most of the headlights need to be made or be able to adjust so it fits the road regulation of that particular system of use; since the projection of the light beam is the completely the opposite of the other road system.

 

What is Auto-Leveling (Electronic Self Level)?
Auto-Leveling is the new feature introduced in the late 90s.  It basically is that a headlight has a motor built-in which operates the headlight projecting angles (up and down) either by car's computer automatically or there is a switch inside the car which you can manually adjust inside the car.  This feature is to provide the best optical angle for the beam output, therefore maximize the visibility for driver while not blinding the upcoming traffic.  Originally, it was only offered to top of line models, now it becomes more and more common on all European vehicles.  If you originally don't have an Auto-Leveling headlight, upgrading to a headlight that comes with Auto-Leveling motor and feature will NOT make your car to have Auto-Leveling, because Auto-Leveling has to do with more than just the headlight upgrade.  It also has to do with re-programming of car's ECU (which only dealer have the machine to perform) plus some extra wiring harness and adapters for the Auto-Leveling plug.  Most of the Mercedes, Audi and Volkswagen's Auto-Leveling plug are located in the same plug where the low beam/high beam/parking light is.  while BMW usually has a separate plug just for Auto-Leveling.  To know if your car has Auto-Leveling or not, simply turn on the headlight, if you see the headlight going up and down for a few sections, that means you have Auto-Leveling.  For BMW E38, E39, E46, E53 X5, you can also check if you have this plug in the back of the headlight?  If you do, you have Auto-leveling model.

What is Pre-Facelift and Facelift?
As you might or might not know that a normal car's production period (a chassis) is around 4~6 years and in between, car manufacturer usually will make small editing on their design after 2~3 years of the first introduction, to update the car's look.  Therefore, before the small editing while stays at the same chassis is called Pre-Facelift literally.  And Facelift is obviously talking about AFTER the editing on the design, or also called Post-Facelift.

What is Clip-On and Screw-On?
For pre-facelift E46 Coupe and Convertible, BMW has switched from the 99-01 Clip-On type corner light to the 02-03 Screw-on type corner.  Clip-On and Screw-On is referring to how the corner light is secured onto the car.  Clip-On means by clips and Screw-on means by screws.  They are not interchangeable.  Here are 2 photos to show you the difference:
