Well I have searched thru old posts here and on the web and I am unsure as to the correct part # for the new roof marker lights since different ones are shown everywhere.
I have seen them advertised as part # 19170450
http://www.gmaccessories-direct.com/...oducts_id=3774
and also as part # 19156090
http://www.gmaccessorydealer.com/det...?prod_id=55073
and GMPartsdirect.com lists both models.

Does anyone know which model is correct and is the new and improved version?
Thanks...

 

19170450 is the most recent kit.
