    1) Low beam burned out, hi beam ok
    2) LAMP error in the display all the time
    3) Inspected old low beam, filament was melted. High beam bulb looks fine
    4) Got replacement bulb, installed good high and low beam
    5) Lamp error is gone, but still no low beam
    6) New bulbs works as high beam
    7) If I put a bad bulb in the high beam, I only get a LAMP error when I turn on the high beam

    Normally I would say blown fuse, but not on a Canbus system.

    If this was a bad wiring connection it would still show a LAMP error even with a good bulb, right? And the original bulb did fail. Do I have do maybe do some kind of Canbus reset, and how? What else could be wrong?

    Did you start the bike?

    Pretty sure the low beam doesn't illuminate until the engine is running

    The new bulb could be defective.

    Sometimes it is the simple things which turn out to be the culprit while we
    are agonizing over all the complex stuff which "might" be the cause.


    There is an old story about a toy train not working on Christmas morning. The Dad is
    checking everything, using a test meter, looking at the transformer, checking the track, etc .

    And then Mom walks past and plugs the power cord into the wall receptacle and the train works :D

    We have a winnah! I always have the high beam on, and that does come on without starting the engine, I never noticed that the low beam only joins it after starting the bike. Doh!

    Just like me trying to troubleshoot my buddies outside light after he tried to fix it for an hour. I tightened the bulb another 2 degrees!

    I don't believe you will get a LAMP caution when the high beam is burnt. Should be obvious. Then again, it wasn't designed to have the high beam as a running light. :huh But you say you did so I'll take your word. Wish I had that problem. Snow sucks.

    It's a lesson that I learned the hard way, and more than a few others have as well.
