    Sat in tonight turned the engine on, turned the headlights and they both stopped working at the same time!
    Checked fuses (the ones labeled as headlights) they seem ok.

    Full beams work, dipped lights work too, strange:confused:

    I dont think its a case that they burned out naturally at the same time as i only replaced one of the headlight bulbs about 9 or 10 months ago
    I also had some alternator trouble earlier this year.

    Vw pasaat 2005 b5.5
    Any ideas??

    If your dipped work then what's gone ? The Sidelights ?

    Anyway, it's unlikely that they both go at the same time.... but still possible. Try a new bulb ?

    As i said, the main headlights are gone. The high beam works and so does the low light the daytime light, whatever its called.

    Seems unlikely that they both would blow naturally at the exact same time?

    DRLs or sidelights, not dipped beams. The "normal headlights" *are* the dipped beams.

    If it isn't the fuse; there is a chance that the fuse is too high rated and a power spike happened which took out the bulbs.

    Yeah, your dipped lights are gone.

    I've seen it before. They live the same life after all and same level of use.

    Plus when one went it could have been enough to take out the other. Replace the bulbs and see how you get on but at the moment, it shouldn't be of any real concern.

    Local scrap yard ? That kind of motor is a dime a dozen.

    Motor Factors aswell..

    You'll need to cover that pretty quick.

    I used to have a 1999 BMW 316 estate, and if you turned on the engine with the headlights on it was about 50/50 you would blow both bulbs. Was told it was a common enough thing with the particular bulb that it took.
