Rear mirror problem

[MPRCTCL]

Just picked up my ‘08 and at night, I get these evenly-spaced vertical reflections of bright lights in the center, rear-view mirror. Anyone else seen this and (fingers crossed) is there a free or cheap solution?

wow , i never noticed that! i'll have to check mine next time i drive at night.
even more wow... you got a picture of it!
did you try turning off the auto dim function ? maybe it will go away then.

Update

The selling dealership explained that what I was seeing was the LED marker lights on the Tahoe. Um, no, I don’t think so.

Sent a a new pic of a flashlight in the mirror and now he isn’t commenting.
