LED Headlight swap

Hello, I have a 2024 F250 XL and I just swapped out the stock low beam headlights to LED. The headlights work, but now when I switch on my light bar I get a buzzing sound from under the dash near the Light bar switch. The light bar is connected to the high beams so it can only be used when the high beams are on.
The buzzing is only when I switch on the light bar, and not when I just have the high beams on.
The buzzing was no there with the stock low beams.
Anyone have an idea what might be causing this?

Where is the light bar getting its power from? Not the headlights I hope.

Incorrect installation would be causing it

You say you swapped out the stock low beams. I'm curious as to if things have changed betweem previous years set up and 2024. Previously the halogen headlight trucks used H13 bulbs. In those trucks all 4 headlights had both high and low beam. There was no such thing as certain bulbs being strictly high beam and the others being strictly low beam on those trucks.

Thanks. That's why I asked. I'm familiar with 2022 and older halogen trucks but not so much with 23+. My 2023 has factory LED so I haven't really had a reason to mess with them like in previous halogen trucks I've owned.

Problem solved, when i removed the drivers side headlight, the wire for the high beam came apart. once I fixed that everything worked correctly and no buzzing noise when switching on the light bar.
