Whistle from LED bar fix?

Hi PP, just wondering if any of you have come up with a fix, my LED bar, mounted on the bull bar has quite a whistle from the mounting bracket. I was thinking of filling it with silicone or something, just thought Id check and see if anyone has come up with a better idea?
cheers

If you can fill the gap with closed cell foam, that would be better than silicone. It would be easily removable if needed.

Are you sure it is the mounting bracket? One #1s ute we finally identified the whistle as emanating from the corrugated conduit around the power cable. We filled that hole with Si and noise has gone.

thanks, Im pretty sure its the gap as I tried wrapping it in electrical tape and it reduced it, I might do some more investigative work and see If I can get some foam. cheers

Mine whistled, I adjusted it so it was perfectly vertical, whistle gone.
