They would not put a "tint" on the headlights. On the pic in the configurator, it does look like the housing pieces that were silver/chrome before, are now painted black. The pic of the Model 3 on the configurator shows the silver pieces in the headlight but the Y's are black... interesting.
I would be very surprised if they actually did this. I'll be looking forward to seeing new Y's delivered in the next few weeks!
I got my headlights painted black on my 3 for $500 (Yeah, I know, but the chrome bugged me) so if Tesla is now doing this then that's $500 I will save in the future on my next Tesla!
