Off Road LED Light Bar Noise Fixed

I had a loud whistle or frequency sound on a GMC duramax truck. turned out to be the aftermarket off road light bar. I bought door edge molding but it is also common to use foam weather stripping. I hope this help as my guys spent way to long diagnosing the problem. Thanks for watching and subscribe to our channel.
