led light bar

Installed a 50 inch curved led light bar a few days ago mounted it on the factory holes where a few roof rack would go and i was driving down the highway and it is really loud like vibration i checked the bolts and eveything is tight, anybody have any suggestions

 

Dont have a light bar but just an idea if you don't already have something like it is to pick up some rubber washers from ACE Hardware and place them in between the bracket and the roof.

 

That sounds like a good idea ill try it thanks

 

any pics? I just got a curved 50" also

 

Here is my mounting suggestion!

and.....don't forget this "wind-whistle" mod!

 

No light bar here, but my Yakima roof rack does the same thing If I don't have the fairing on it.

 

Depending on the speed of travel and space between the light bar and the roof line you're going to get noise. Whether it's a high pitched whistle (small gap), or a low pitched "thumping" (larger gap). If the bolts are still tight, than its just the different frequencies of of air traveling through a tight space. Only way to eliminate this is by getting rid of any gap.
