    Got really confused today.. I was looking at upgrading the bulbs so went to

    www.carbulbsdirect.com and www.powerbulbs.com

    Both state that the dipped beam is an H7 and the high beam is either H4 (1996-1999) or H1 (2000-2003).

    My car is a 2001. My dipped beam matches the look of an H1 and my main (high) beam match an H7 in appearance. Also, my dipped beam is the inner most followed by high beam then sidelight (from grille outwards).

    This is different than the websites and my bruvs cars which is 1998 A3 Sport - his dipped is in the middle and high beam is closest to the grille.

    Can anyone confirm what the differences are / changes were to the headlights when there was a facelift between 1999 and 2000.

    I though maybe migh lights had been wired up wrong but looking at the connectors, wires and casing they can be.

    :)

    Ok im going to go into as uch detail as possible with the 8L series of car from Audi....

    Starting with the A3

    1996 - 1999 on a prefacelift the headlight looks like this...
    [​IMG]

    The bulbs that are needed for this are as follows:

    Dipped (main) - H7

    Full Beam - H1 bulb if your headlight switch looks like this
    [​IMG]

    Full Beam - H4 if your headlight switch looks like this
    [​IMG]

    The H4 bulb has two filaments and accomodates for the front fogs aswell as the full beam.

    A3

    On a 2000 - 2003 Facelift The headlight looks like this...
    [​IMG]

    The bulbs that are needed are as follows:

    Dipped (main) - H1

    Full Beam - H7 Only one size as the facelift cars with front fogs have them integrated into the lower bumper apron.

    S3 1999 - 2000 On a Pre-facelift have these headlamps
    [​IMG]

    Dipped (main) - D2S (xenon gas)
    Full beam - H1 (normal halogen)

    On the 2001 - 2003 Facelift This is the headlamp style (exactly the same as A3 Facelift)
    [​IMG]

    With the bulb sizes being

    Dipped (main) - D2S (xenon)

    Full Beam - H1 (normal halogen)

    The S3 Pre-facelift and Facelift both come with front fogs as standard therefore the headlight switch looks similar to this...

    Thansk, excellent explanation...... but when I physically look at the bulbs the dipped resembles an H1 not H7 and vice-versa for the high beam.

    H7 - fatter, larger back plate
    H1 - longer, skinny, wee'r bulb

    I'll get pics......

    Many Thanks

    :)

    Can anyone confirm if the above is incorrect?

    It looks like
    H4 foglight
    Under that looks like a H1 full beam
    H7 Dipped beam
    Indicator bulb

    Early glass faced lights may well have had the fogs built in like my old A4 did...

    I have a 1999 a3 and the h7 dont fit dip beam. I have 3 connecting terminals on the bulbs that are on the car now. The h7s only have 2.

    Look on the front of the bulb that was in there, it says what bulb it is on it.

    Are you sure you're looking at the right bulb? The H4 fog-lights/full beam have three connectors.
    The H7 has two connectors.

    On ther prefacelift A3, the inner most lights are Fog/full beam H4, under that is the 501 side light, on the outer is the H7 main beam.

    The picture above in this thread doesn't match the pre-face lift A3.
