Black Mountain LED Light Bar Noise Vibration Dampeners for Dual Row LED Light Bars SET OF 4 Tired of the Dreaded Light Bar Whistle? Because all light bars have fins for cooling, all makes and brands have a chance to whistle at highway speed. The noise is coming from the wind whipping past the cooling fin blades on the back of your new LED light bar. BUT with these Vibration Dampeners this will help to eliminate the vibration coming across the cooling fins. Install these about 12" apart (see picture #2 above) this is what we have found works, however all light bars are not made the same and may need extra dampeners. This is for a Dual Row LED Light Bar and will not work on a Single Row Light Bar.
