I have the subject light bar installed on my Rubicon, I am looking for a light cover to fit either neoprene or plastic. I love the way it looks and the light it puts out but that damn thing whistles at 50 mph and doesn't stop until I slow down or stop. Any ideas?

 

I may be mistaking, but I am fairly certain that Rigid sells weather stripping like material to put on the rear fins. If not, I would search your local hardware store.

 

They have little clips that you attach to the back, they typically send them to you free of charge, just give them a shout.
