Just replaced my brake lights with led on my 2011 f150 3.5 ecoboost. These led are plug and play, they worked fine for a few hours. Now my brakes don't turn on? When I put the turn signal on , it flashes fast and my rear brake lights all flash at the same time!? Checked fuses and all seem to be ok, not sure what is causing this issue or how to fix it or is this something that needs to be fixed by dealership? Any help will be greatly appreciated. Thank
