VW/Audi

For normal (old) headlight. Light bulb are either H1, 9006, 9004, H7.... etc.
For the REAL (new) HID headlight, I just know it is D2S. I saw some HID Conversion kit for non-hid headlight. It has something like H1 D2R/D2S.

My question is what is the name of Audi HID headlight bulb?? just D2S?? or (just an example) H1 D2S??

HID bulbs are D2S (Projectors) and D2R (Reflectors).

That D2R bulbs have masking and D2S do not. They are otherwise identical

I think you are refering to a HID bulb that has an adapter base installed to mount in an non-HID housing. H7-D2S would be for a Halogen (Non-HID) projector housing and a H7-D2R would be for a reflector housing (note: Audi did not make a stock HID Reflector headlight)<ul><li><a href="http://www.eur.lighting.philips.com/automotive/html/input_products_xenon_range.html">Xenon Info</a></li></ul>

Thank you jbaulsir
so that's mean all new Audi, VW, BMW, some high-class Benz all are using same style of bulb (D2S) because they all has HID projector housing. So i can go to Audi and buy a pair of HID bulbs to plug into BMW.

Are there any after-market bulbs??

but I think they have reflector type HID lights. Also as long as the bulb type is correct the source is not important (like buying a replacement H7 bulb at a BMW dealer - it will fit a so equipped Audi).

And yes there are other sources for HID bulbs but go with a reputable manufacturer, the bulbs are expensive to replace.
