High-pitched ringing noise

[joec]

I wonder if the pitch of this noise is in the same frequency range as the constant Tinnitus I have ringing in my head 24/7?

I have the same issue. I'm wondering if it's effecting all cars but only some are hearing it, or only some cars have the issue. Glad someone figured out it maybe the window switch lights. I can confirm that turning the headlight off makes the high frequency sound go away. It's very distracting to me and and starting to give me a slight headache. I don't think turning music on is a good solution. I wish I knew about this issue before i got my LAT25. I hope there is some kind of a resolution to this.
