    Modifying lights to led

    I have found an interesting mod for the xr 1000 to change standard globes to led lighting, this pn 2019 model. Osram supplies a kit for the h7 globe replacement,with an led light.
    Many owners i hear are experiencing problems with the lamp fault on rhe dashboard. Mostly seems guys have no idea why there is a fault.
    Reason is simple. The xr1000 is supplied with a canbus wiring system, this is a form of plc control system which can allocate operands in the elecrical system with multiple outputs. So there needs a feedback from devices to say if operating or not.
    On the xr it tells what voltagw and current draw the bike haa for various devices and sees an led lamp as too low current draw as led lights draw less current and then appear as if the globe is not functioning correctly, therefore the intermittent fault on the dashboard.
    This fault only appears on the main driving light and not on the bright light as there appears to be no voltage or load monitoring for bright light.
    The solution is a canbus controler oe in simpler terms a resistor between the running light and the canbus system.
    This fools the canbus system into believe there is  load by creating a resistance in the circuit where in fact the globe has. Lower load.
    Problem solved

    There are already plenty of decent Canbus compatible lights available that have no such issue. I have Auxito LED H7s in my bike and don't have any issues with errors, lot of people use the Techmax LEDs, they're mostly the same.

    Old news l'm afraid...we've all known this for several years. Many of us have had LED headlamps fitted to our Gen-1's for years with no issues.

    What would be really useful is if BMW's engineers didn't insist that the current draw on each lamp exactly match that drawn by the OEM bulbs they install during assembly. The Canbus test that is performed on power up should determine only that there is some current flowing in each circuit to verify that there is a bulb there and if it's incandescent the filament has not burned out.

    A fallback would if Motoscan or the GS911 folks could develop code for their OBD2 devices to tell the bike that it now has LED bulbs. This is commonly done for BMW cars. I've programmed my 435i to think it has LED turn signals, so I was able to swap the incandescents out for LED without a fault being detected.

    I had the technician do the same with the official BMW OBD2 program for my S1000XR on it's first service.

    Makes sense but the indicators came with both LED and incandescent options, headlights didn't. I get issues with the sidelights but none at all with the main bulbs, the sidelights throw an error when the bike is off despite working just fine but then when it's started, the error goes out. Interestingly a friend running the exact identical sidelight bulbs doesn't get an error at all. I think maybe it has something to do with the DRL strip in the middle causing sidelights to not be on normally so it's not causing an issue. I hate that my bike doesn't have the DRLs because even though LED bulbs are cooler, they are still cooking those little sidelights and the sidelights are actually getting a bit of a "tan" going on. I'd ideally wanna see more light settings on the bike, like, just sidelights, no low beam or just low beam no sidelights, etc. Unfortunately even though mine is a full spec Sport SE it didn't come with the DRLs so I don't have that functionality.
