I just bought a light bar and as usual it sings in the wind, heres a easy fix and only cost 5 bucks. ill post a link below on what i used.
This is super simple process just take the door sealant and put it on the back most ridge on the light bar where the wind is going to bounce off the windshield and blow against the light bar.I took it for a drive and there was no noise at all after the quick fix!!
