Hyper flashing on passenger side front and rear

[Tat3]

Can someone please help, here’s the situation it’s a 2011 gmc sierra I do have aftermarket headlights and tail lights and they are not LED although I do have a LED strip on the front and rear of the headlights and taillights, that being said I’ve had those for 5ish years… the hyper flashing started about a year ago and I cannot figure out why, they initially started intermittent and over months time it got worse just hyper flashing more and more and now it’s pure hyper flash this is happening only on passenger side my driver side still works perfectly fine, I’ve concluded it’s not the headlight or taillight because I’ve had them so long it would do started when I first got them, I’m thinking bad ground or bad connection somewhere idk what else to do, I also have a tailgate bar that I installed 2 years ago and the passenger side worked perfect with that as well, not sure what caused this or how to fix

Disconnect all aftermarket LED lighting and re-test.  Does it still hyperflash after that?  So unplug the strips on the front and rear, and the tailgate light bar.
