HID headlights are less common, and they work by igniting a gas—most often Xenon—with electricity inside a bulb. They emit a white or bluish-white hue. LEDs are a far more advanced technology. Green dot on the parts sticker on the failed headlamp, continue regular troubleshooting on the xenon light. Case B: No green dot on the parts sticker on the failed headlamp: If both headlamps have failed: The xenon control unit and xenon bulb from the failed headlamps must be replaced. If only one headlamp has failed: In the US market, BMWs equipped with bi-xenon headlamps also come with adaptive headlamps. Foglights were standard on the 3.0i and 3.0si, and optional on the 2004-2005 2.5i models. The adaptive headlight function itself is the swivel of the headlamps left/right up to 15° based on various sensors and steering input. 2. The F32 headlights will work with the F82, but make sure it is the pre-LCI F32/F82 headlights. The F32 LCI headlights will not work. This has been covered in a couple of threads in the F32 and F82 subforums. 3. You do NOT need the front facing camera to use the LED headlights. 1) Glare. While the brightness of xenon headlights may make your driving easier, it won’t make driving easy for other drivers on the road. The brightness can cause glare to reflect in their mirrors, which will make it more difficult for them to see the road. This could cause an accident or create a road rage situation where they get upset The bi- xenon bit refers to the electromagnetic actuator that moves the shield out of the way when you engage the main beams. This allows more light out of the projector. The main advantage is increased efficiency, 35W of power in HID puts the same light as 100W or so in a Halogen incandescent bulb. The answer: Not necessarily. There is no clear-cut, standout technology winner among among HID, LED, and xenon headlights. While there are poor and very good performers in each variety, none I don't think the light bulbs are broken, because I can see all light bulbs are on. There is no individual cornering light in the Bi-xenon lamp assembly. On recent models, there are two methods of improving the lighting when cornering. A. Integrated curve illumination. This optimises curve illumination by the use of small motors (E1m2/E2m2) on 68Us.
