    Hi everyone,

    On my 2022 Bonneville T120, the headlight has an LED signature that changes depending on whether the headlights are on low beam or high beam (and it works normally). There's also an H4 bulb, and it's on this bulb that the Hi beam dos not work. Cheked and changed the H4 bulb and Hi beam still not working.
    - I tested the H4 connector in the headlight bowl; there's power on the Lo beam but nothing on the Hi beam connector.
    - The Hi beam indicator on the dashboard works normally ( It does light on with switch on Hi beam position)
    - I connected the DealerTool, which allows you to perform a lighting test, and within the test, the H4 bulb works normally (both Low and Hi beam work )

    What's the problem ?

    It's pretty straightforward

    Someone gave me the answer and I would have found out if I had read the manual:
    I didn't know there was a "headlight dip switch" and was trying to put the hi beam on and off with the "Daytime Running Lights (DRL) switch"
    I feel pretty stupid about this ...
