thanks in advance </div></BLOCKQUOTE>

Matt I paid the dealer $700 for lights and install.I would not suggest doing it yourself becuase there is a noise problem rite now.They need come up with a gasket of some kind to install at front of the light to stop air flow from getting underneath them. </div></BLOCKQUOTE>

I would make sure the dealer places a call to GM technical assistance and have TAC open up a case. These cases are reviewed and sometimes referred to engineering. Engineering should then look at the problem and come up with a fix.
From looking at the photos of the light bars, it would appear, at least to me, that a simple "T" molding strip would cure any problems of air getting under the bar.
The vertical leg of the "T" strip would slide between the roof and the bar, allowing the two horizontal legs to overlap the light bar and the roof. This should (and I say should not would) prevent air from entering under the light bar.
