All lights Flicker when Turning or goin over bumps help

sup everyone im new to this site so thought id start off by sayin Hi...

OK i just bought a 2003 GMC yukon slt awd with air ride. Now i noticed when i turn corners (kinda hard not railing them but not drivin like a grandpa) that the head lights, fog lights, even dome lights (if on) will flicker... this doesnt seem normal to me but im just wondering if this is the traction control or air ride taking from the central power or no

i put a red top in since i noticed the flickering (came from my old truck) and it still does it. most the time it takes a pretty long corner for it to act up but some times just a long bumpy patch in the road will do it to. its done it a few times when drivin straight on a smoother rd also. ive checked all terminals both on the battery and the altinator and im at loss can anyone help thanks

Check your wires, ground and all that. If they are corroded consider the big three. if they are loose tighten em up! HOpe that helps some
