I have 2004 Cayenne turbo that needs a new head light. I checked ebay and found there are halogen and xenon head light. How do I know what type that I have? thanks for your help.


ALX5.

 

By the color of the light. Halogen will be a "warm" colored beam. HID-xenon will be a bright white color. You could also look on the back of the headlight assembly for a ballast unit (needed on the HID lights) and the associated High-Voltage Warning sticker.

 

HID/xenon will also self level when you turn them on. You'll see them dip then rise.

 

just compare pictures on ebay and your car. HID = lens, halogen means reflector. air suspension cause automatic headlight leveling with halogen also.
