Ok I️ installed ltz headlights on my 2015 suburban LT and for some reason I’ve noticed that when the battery gauge goes over 14 they start to flicker

Are the Ltz headlights HID's?

the flicker is probably a ground issue, get a meter and test each side for the ground wire and run a wire ground directly to the frame (one for each side), (don't cut any factory wires-just patch in a ground) be careful GM likes to play roulette with wires one side wire color may be a ground and the other side ground may be a different color. it wont hurt anything to do this and you will know right away if that is the issue for sure or not. there is almost always a spot near the headlights to attach a ground you shouldn't have to drill or anything, just use the same meter to verify it is a good ground location and not plastic or aluminum.

This is crazy because on the old headlights I️ had 50w hid set up with no problem

Grnds were and usually still are black. One thing gm kept consistent for yrs and diff blues for front turn and yellowish greenish for rears but this all may have changed.

Indeed!

OP-
Why did you replace the original HID's? Were the ones that you installed new or used? Higher wattage?

just plugging in the HID's probably not going to work correctly...may even need reflash, nothing is simple anymore
