S60: new headlight bulb doesn't do it

    I've been riding around with a "dipped headlight bulb out" error
    for a while, so today I tried putting in a new bulb. It took me a
    few minutes and a flashlight to figure out how to physically make
    the switch, but the unit still doesn't work. Is there some other
    possibility I should look for - like a fuse dedicated to one
    headlight bank only, or something - or do I need to recheck my
    connections even more carefully?


    Thanks,
    p.

    First see if the lamp is truly not lit. The error message may itself be in error.

    The dipped beam is the low beam make sure that you did not replace the
    high beam by accident

    In the bulb failure relay there are little shunts - a low resistance
    that the relay uses to measure the current going into the bulb. This is
    the info that the relay uses to turn the bulb failure light on. These
    burning out are a fairly common problem. There are different ones,
    depending on the headlights.

    Would this shunt going kill the headlight too? I think tommorrow
    I'll see if my mechanic will take a look at it. It is the
    headlight that's not lit, not just an errant warning message.

    Thanks to all who responded - I've been offline for 4 days due to
    serious ISP error.

    Yes, while I've never dealt with the solid state sensor used in the S60,
    a burned out shunt will indeed kill whatever light it feeds. Makes me
    like the old electromechanical sensors a bit more, very clever design
    they used.

    Turns out it was something related to the interior fuse panel. We
    checked the hood compartment fuses - nothing. Then he went into
    the interior panel. Not sure what he did - he speaks with a thick
    Greek accent - but I soon had my light back. I supposed it was
    the fuse, though he made it sound more complicated than that.

    Thanks again to all.
