Map Light Flicker?

Hey - just to preface this, I've used the fabulous search function we have. I have found nothing that's comparable to what I have going on.

I DID PUT LEDS IN ALL INTERIOR LIGHTS AND HAVE HAD THEM SINCE THE FIRST WEEK I BROUGHT THE TRUCK HOME (06/18)

As I approach my truck the interior lights turn on, no flickers, nothing weird. As I open the door and turn the truck on that's when the flickering starts. It'll last a good 10-20 seconds looking like I'm having a disco party of 1. Then it'll return to normal.

Anyone have any ideas on what's causing this?

 

Since no one else responded, I'll throw in my two cents. I'd look at whatever systems/functions are firing when the door is open, because maybe there's a fault/short in it. Door chimes, or door sensor or something like that? Something that's interrupting the electrical when it triggers...

Wild guess, not too helpful. Sorry. Post count+1 though.
