I added a little baseline dim to the auto rearview and drivers side mirror by inserting a piece of window tint over the windshield facing sensor. I just cut a piece off the roll and slipped it inside the mirror over the sensor unpeeled. Makes the mirror think it is darker outside than it is and adds a little dim at night. No difference during the day from what I can tell. Extra bright lights still bother me a little and I think it's because the mirror won't dim as dark as it used to when it was new.
