Re: Factory Light Bar Opinion
I have the orange marker lamps. The mounting base is similar to the off road lights, and yes they both had major wind noise issues when they first came out. The rattling and shaking produced a loud continuous fart sound inside the vehicle, that was annoying as hell.
Hummer put out an order to dealers to stop installing them and took several months to come up with a solution. They did come out with a fix that comes with all the new units. The fix has worked for my vehicle perfectly. That noise had me prepared to rip them off the roof and throw them away, but thankfully it is now a non issue.
I would base your decision on the performance of the lights themselves, and not on the wind noise issue. I believe they are fine now.
