Buy a D2S bulb. The high beam activation of the stalk initiates a flap in the headlight that allows the beam to be thrown further. The bulb is just a bulb...there is no low or high version.Hello everyone, I have another problem:
2006 X5 3.0i
Active bi-xenon headlights want to replace bulbs and don't know whether to use standard D2S bulbs or if they have to say high And low beam.
Not sure how old the bulbs are in the car now.
If you have adaptive bi-xenon headlights...you'll have the following option codes:
- S524A Adaptive Headlights
- S522A Xenon Light
Bi-xenon headlights uses one bulb for low & high beam. When high beam is required...when you initiate the lever...a flap is actuated in the headlights that allows the beam from the bulb to be thrown higher/further.
The inner bulb (next to the kidney grills) is only for flash-to-pass.
