Good afternoon g37 community,

One of my drls is burnt out ao I am upgrading but figured I would do the headlights while I am at it. Having changed juat one headlight I turned my lights on to ensure it worked before moving on to the drl. I am hearing a buzzing noise coming from the headlight. Normal at all? Car is turned off and the bulb is of a different kelvin than the one in the passenger side at the moment.

** did a bunch of googling. Seems it is a pretty common thing. Can't hear it in the cabin so I guess i just never heard it before. **
