Hi, new here, I have a 56-plate 2.0TDI Sport
I'm justwondering if someone could answer a question about headlight types and when they were introduced (I've searched but not seen anything definitive).
Am I right in thinking this about headlights?:
that from 2003-on (to 2008?) most A3s had the standard halogen headlamps for dipped and main beams:
Optional were single xenon (outer lamp) with a halogen inner main beam lamp (commonly found on S-Line and S3). The inner halogen main beam "cuts" into the outer xenon lamp:
Then around 2006 were the xenon lights changed to bi-xenon? (more of a black surround and smaller inner lamps). Do these have DRL on the inner lamp? Or is it only some? (do some still have a halogen main beam and single xenon in this design?). The reason I ask about these particular lights is because I've seen them on 06 cars and I thought DRL came in later; also mine's a 56 and doesn't have DRL but as DRL have come in due to EU-law (and not just some current trend) shouldn't it mean all cars made from a certain age have DRL regardless of halogen or xenon dipped/mains? (phew! )
Then 2008-on are the chrome/blingy with halogen or xenons with daylight running lights etc:
It's these 2006-on xenon lights I'm interested in specifically; the inner lamp isn't the main beam but a DLR? Ie the headlights are bi-xenon so just use the outer headlights. Does anyone know what would happen if you put a regular non-bixenon D2S HID bulb in one of these units? Will it just produce a standard dipped beam pattern?
Thanks for any info.
