cant seem to find a good answer but i used to have 4 KCs on top of my jk and the wind noise got old after awhile. i was looking into a LED light bar. hows the wind noise with the LEDs if any?

Depends which brand you get. Many put door trim pieces on to keep the rear fins from vibrating, mine doesn't make any hum.

I have a 50" and some times it whistles

My 50" Rigid Industries had a god awful whine. I posted a thread about it awhile back and even drew up a sketch of a stupid rubber isolator idea that I had which could be stuffed between the fins. Turns out that the Rigid guys must be on this forum because a few months later I read how Rigid is handing the EXACT rubber isolator free of charge to anyone who bought their light bar. The isolator works like a charm, not a single sound now. Though, over time the isolator has gotten a little loose and can slip out. My suggestion is put a dab of black RTV to hold it in place

My KMA Fabrications lightbar with two Rigid-style LED lights doesn't make any noise that is noticable over the stock Rubi tires. Even with the top and doors off.
