D5S bulbs do not require AC power to ignite and burn the gases inside. As a result, D5S bulbs produce substantially less light than D1, D2, D3, and D4 type HID bulbs. The D5S Xenon HID technology is simpler in design from conventional Xenon HID systems, and can powered up by directly applying 12V to the bulb. on a non AFS car pins 1-4 control headlight range. on a AFS car its only pins 1-2 and pin 3 is blank and pin 4 is power and 14 is ground. The AFS cars have another module built into them(3 total, Xenon control, LED control, and AFS control) This is the theory at this point so Ill let everyone know how it goes. This gives you a whiter beam (xenon-look) but reduces light (lumens) on the road. Unless the cosmetic appearance of your headlights matters, I would stay with clear bulbs. Consumer Reports did a comparison a few months ago on top aftermarket bulbs and determined there was no discernible differences in performance, irrespective of cost. The benefits of xenon lights are that they are much brighter and last longer. The number one reason to use them, however, is for safety. Xenon headlights typically allow you to see two to three times further ahead than halogen headlights. You will also be able to see better in inclement weather and at night. Anytime you hear "bi-Xenon", you're not getting two Xenon bulbs in one headlight housing. With bi-Xenon applications, there's a little solenoid that activates when you switch on your high beams. The solenoid flips the shutter inside the projector out of the way, unleashing completely uncontrolled light. Up and down is self leveling and is required by US law. Side to side movement is adaptive lights and is an option. I cannot see under any circumstances replacing xenon with halogen. As Al Kazaz said, purchase a salvage part. I suspect you will have to get it programmed in any case (replacement xenon or replace both headlights with halogen. I know there are a lot of non-Xenon projectors, for I had them in my BMW, but I don't know if all Xenon headlights came out factory as projectors. I didn't know Xenon conversion kits were illegal in most states. I thought it was just the 10K and 12K colors, since they are too dark. The location is asked it depends on the market area. US/ CAN have either the LED or Xenon plus - European markets have matrix LED which is far more advanced. I have a PP with Xenon plus, and truth be told this is way better than my A6 2.0T that i had a few month ago with Xenon plus. To me it's adequate and does a good job. FZTZ4.
